Hurt fails to mention that only 424 members of the IAU voted, leaving over 9,500 members voiceless, and the IAU has not admitted that the vote was problematic. There will be a debate soon about Pluto on teevy. Stay tuned. This debate is far from over.
Maybe science don't consider Pluto as a 9th planet. But for God Pluto still represented 1 of the highest individual in heaven one of the 9 archangel of God. That represented by two statue angels and seven candle stick in the holy tent. anything except the 9 archangels are all just a servant angel of the 9 archangel.
The One who has the largest satellite represent the 9th archangel of God and that is pluto.

Size did make a diffference but also placing and the way it rotates around the sun. Generally though, if pluto were as big as say, jupiter, then it wouldn't be booted imo.
What would happen to pluto when our sun reaches the red giant phase? Will it melt since it's practically ice? And what about jupiter, saturn, uranus and neptune.
Out where Pluto is, it will still be pretty cold. But it will be somewhat warmer, so Pluto (and all the outer planets) will most likely go through some changes. But since we still know so little about Pluto and its atmosphere, I wouldn't be confident making a prediction. Jupiter, however, may find itself in the habitable zone briefly, and it's possible that its moons could support some forms of primitive life for a brief period of time.
How brief? a couple million years or a few decades? Me and my mate think in the future we should go to Titan and brn the methane to make water and fuel, and with the reduced gravity we can fly ornithopters. Is that possible?
It's not my area of expertise, but the estimate I see most often is "a few million years."
But since Titan is so small, it would have a hard time maintaining an atmosphere that would be thick enough for humans to breathe once it warms up that much. Other forms of life *could* evolve there, but in evolutionary terms, a few million years is a blink of an eye, and such life probably wouldn't get past the very simple, early stages of evolution before the Sun collapsed.
I like how simply put this is. Perfect for those people who argue about Pluto just for the sake of arguing. Most don't know why it's a dwarf planet, they just no it's not a planet anymore...
Many asteroids do, but I don't think any have been confirmed around a known dwarf planet. However, since dwarf planets are very small (and therefore hard to resolve), moons may be lurking undiscovered.
Having a moon is not that unlikely. All a moon is, is a piece of object caught by the gravity of a bigger object. Now, how many objects are there in the universe moving around all the time?
does anyone thing about the gravitation of pluto and its moon??? i mean wouldnt that have some effect on how it would orbit its sun???
think about it. its moon is like half its size so should its gravity effect pluto in some way. that could explain the odd orbit and i dought plutos moon is orbiting as flat with the sun as the planets. im thinking the moon moves the planet a little off its course because the moon is not only orbiting pluto but the sun too. so it would be drown to the sun also.
Plute and it's moon Charon have a common center of gravity that is located not in Pluto but in the space between the two objects. Because of this, it can be said that Pluto and Charon orbit each other!
At 2:10 he says that Plutos' orbit intersects with that of Neptunes. If so, does that it mean that it is possible for the two to collide? I understand even if it is possible, the chance of that would probably be 0.01% to actually happen, but still, it's an interesting thought I think.
As Pluto crosses Neptune's orbit, it's actually above (or below, depending on your point of view) the plane of Neptune's orbit. So even if they're both in the same place in map view, they won't actually hit, until something shifts the orbits again.
Gosh, the de-planetezation of Pluto really pisses me off!!! It's just like some idiot just decided that 2+2=5!!!!!!No fair!!!! Pluto will always be a planet!!! to me
ok this will stir some crap around about whats a planet or not...A space probe is being sent to pluto from NASA . It will arrive in a few years. What happends if they do discover real live on pluto Yeah that will throw a Monkey Wrench into the planet definition ..the lest expected Planet (Dewrf) having real live on it .
First of all, whether Pluto has life on it or not doesn't have anything to do with it being a dwarf planet. Secondly, no life can exist on Pluto, as it's too cold.
Jupiter and other planets like Saturn , Uranus ,Neptune etc are fully gas planets not formed fully yet .. so we can consider them as planets cos they are very big compared to others ..and have big G full and have lots of moons , they orbit around sun !
even though they r not fully formed yet or failed planets if we consider atmosphere or no solid mass in it .. they are very big wanderers !!
um lol probbly cuz since jupiter also has the biggest magnetic field in the whole solar system XD and yet it was only belived that it was a faild star cuz it was not big enough or even hot enough. Yet if Jupiter was bigger and hotter THEN we would be living in a double star system XD.
because Jupiter never had a system of planets and satellites orbiting around it and was never the center of a solar system. It also doesn't like to eat chocolate ice cream with Kirk.
This is a huge load of crap.only 5% of scientist wanted to change Pluto to not being a planet anymore.Also according to their definition of a planet Earth, Mars,Jupiter,and Neptune aren't planets either.
Yes, Ceres is also classified as a dwarf planet now. The reason it makes the cut is because, like Pluto, it's big enough to have achieved "hydrostatic equilibrium" -- which basically means that it has enough mass for gravity to shape itself into a roughly spherical shape, but not big enough to have cleared out its orbit and formed into a full-fledged planet.
The folks here who research the asteroid belt tend to think it's the remnants of a planet that never formed, but there's still a lot of discussion about that in the astronomy journals. As for the difference between an asteroid and a dwarf planet -- it's just size. If it's big enough for gravity to make it a ball, it's a dwarf planet. If it's smaller and ends up irregularly shaped, it's an asteroid.
It is denser than some lighter rocks that were around it after the formation of the Solar System. The less dense rocks were attracted by it's gravity and began to orbit. They then clumped together and formed a moon.
Of course it is; everything that orbits the Sun is part of the Solar System. There are loads of celestial bodies in the Kuiper belt (everything past Neptune).
I haven't read the entire IAU document, so I'm not sure if it allows for a binary planet, but I'd make the argument that if a stable binary planet has successfully cleared its orbit, then they would be designated as planets -- especially since it would be very challenging to identify a binary exoplanet as such from Earth.
The clearing of the orbit might gravitationally breakup a double planet pair (where the two bodies are of very similar mass). But then again you could call the Earth-Moon a double planet system depending on the definition used.
And should the Earth still be the center of the Solar System? Facts and definitions change. Pluto should not be treated as the same as the other 8 dominant bodies in the Solar System. Pluto should be treated as more like Ceres and Triton (largest moon of Neptune).
For my whole life Pluto has been called a planet how can a group of people decide how it's classified. They can't just throw out a planet because thats what they think its like saying that certain races aren't human. There might be other rocks similar to pluto but it has always been the rock out of these similar ones that has been classified as a planet. I think this is abserd just changing it like this we have always had these 9 planets and I will always say pluto is a PLANET.
MAYBE Pluto was once a moon of Neptune in which its orbit decayed and became loose that it orbited the sun...who knows? Pluto WAS formed in the primordial solar nebula, so why isn't it a planet? It stopped obeying Neptune's orders probably and became more obedient and respectful of the sun..haha..just think of how funny it would be if our Moon disobeyed the Earth and started its own title as a "dwarf planet Luna"..
fall3n no he ain't he is a drawf because there is too many *simarlarity* planets to pluto so they didin't make him a moon or planet they made them all drawf planets for instance like *mertorites*
Agreed. That is totally true. All of our 9 (now 8) planets suround the sun, including Pluto! It doesn't make sense to just make it vanished from the solar system... everyone calls it a "dwarf planet", but it's a planet in my book.
Just because an object has a moon does not automatically classify it as a planet. Venus also doesn't have a moon and it's roughly the side of Earth. If an object is a planet it needs to have done the following:
A planet is any object in orbit around the Sun with a diameter greater than 2000 km, whose shape is stable due to its own gravity, and is dominant in its immediate neighbourhood.
Pluto isn't a planet because the other planets got jealous. Especially Jupiter. I hate Jupiter.
BRING PLUTO BACK AND KICK JUPITER OUT OF THE SOLAR SYSTEM!!!!!! (xD i'm not crazy, i'm having a sugar rush and a bunch of weird stuff is going through my head)
PLUTO is a planet, but its not considered part of the great 8 anymore. Sedna, Makemake, Eris, and all the other distant objects are usually planets. but stupid picky scientists say that only the great eight are "planets"
oh poor pluto.but,to me,pluto is till pluto,it is still a planet.oh one more time,POOR PLUTO.I love u PLUTO.lol,actually pluto is a planet jus that it is counted as a dwarf pluto,well,thats what i noe lol.I AM ONE OF THE PLUTO FAN,WELL,ANYONE WHO IS ALSO A PLUTO FAN,U CAN MESSAGE ME AND WEE,U NOE,MAYBE WE COULD MAKE A PLUTO FAN CLUB...........lols
Yeah it's not a planet, it's a kuiper belt object, there are many objects like pluto out there, some bigger than pluto like Eris for example. I like the definition dwarf planet. Pluto is really small, smaller than our moon actually.
'any body which orbits the sun, and which is massive enough to have a moon is a planet'
There is no other reasonable means of defining the term 'planet'. Orbit eccentricity, size, and neighbors don't matter. If it orbits the sun, and is massive enough to (at least potentially) have moons, it is a planet. There is more cause to exclude Mercury as a planet than to do so to Pluto, since Pluto at least has a moon.
Then if we are talking about moons big enough to be truly a moon ( > 100 km diameter, mostly-spherioid shape), then these asteroids are actually planets.
The primary feature of a planet is that it represents a gravitational source that causes nearby objects to orbit IT instead of the sun. It is a hierarchical distinction in the gravity system of our solar system. Any object that is massive enough to have moons, which themselves are massive enough to have sub-moons, is a planet.
The ability of a celestial object to maintain a roughly spheroid shape is called "hydrostatic equilibrium." It's part of the definition of a planet and dwarf planet. The majority of moons in the solar system aren't actually big enough to maintain hydrostatic equilibrium.
Yes, but as long as there is at least 1 such moon which maintains hydrostatic equilibrium orbiting a body, that body is a planet. Just because additional smaller moons cannot maintain HE doesn't disqualify the planet classification.
Actually per the IAU definition the primary feature of a planet is the ability to gravitationally clear the orbit of debris. As new debris comes crossing into the zone, it will cleared over a short time scale.
i think the astroid belt was a planet that got crushed because of jupiters gravity pull. my theroy is that there is a planet similar size to jupiter beyond pluto and that pluto and his buddies r just like the astroid belt. lol hard to get this for homework rofl
Why do people get emotional about such an arbitrary thing as the classification of a heavenly body? Because you have a nostalgic childhood memory of learning 9 planets? What a stupid reason, the model of the solar system has changed and still is. You know, Pluto's orbit is actually littered with objects almost the size of Pluto itself? More complex terms are needed to describe what we know is true and to be opposed to this is to demonstrate your own ignorance.
"Oceania is at war with Eastasia. Oceania has always been at war with Eastasia. Oceania is allied with Eurasia. Oceania has always been allied with Eurasia."
"Pluto is a dwarf planet. Pluto has always been a dwarf planet."
Some of us object to reality being rewritten. The new classification makes no sense, doesn't help clarify future cases of newly-discovered bodies, & is highly arbitrary.
If other similar objects are out there with moons >100km then they are ALL planets.
because the Pluto file scientists said so and now millions of children are crying every night..Neil De Grasse is one of these meanies and now the kids are crying..
Well thats cause he didnt mention the differences in the classifications between Dwarf planet and Planets. One thing i know is that if you brought Pluto closer to the Sun it would staart yo melt and grow a tail being that its mostly made of ice.
I think scientists should no longer use the term planet, as it's not scientifically useful.
Star's are well defined by properties such as size, mass, composition and luminosity. And stars go into families accordingly. Asteroids are also divided by what they are made off.
For scientific purposes, ditch the term 'planet', but instead make a similar taxonomy for spherical non-star objects. Divide them in families such as jovians, neptunians, terrestrial, plutoid. Instead of muddling with planets.
that would be a real scene not to miss! but what are the chances? :p
however, FYI, Triton, the largest moon of neptune, will eventually collide into its neptune, or it will shatter and form an extensive ring of neptune, just to the fact that triton is orbting the opposite way of neptune's spin.
no it won't i took about it and asked the same question so no coz while neptune is moving from one direction pluto will take its place for a second while neptune is returning
Pluto only intersects Neptune's orbit when you look at it in map view. But since Pluto's orbit is on an incline compared to the eight major planets, they're not in any danger of actually hitting. It's like two airplanes, on at 1,000 feet and one at 30,000 feet. From above, they look like they're going to hit, but they're actually nowhere close.
Hurt fails to mention that only 424 members of the IAU voted, leaving over 9,500 members voiceless, and the IAU has not admitted that the vote was problematic. There will be a debate soon about Pluto on teevy. Stay tuned. This debate is far from over.

Basic definition of a planet:
1) orbits a star
2) big enough that it's gravity pulls itself into a roughly spherical shape (i.e. hydrostatic equilibrium)
3) has cleared it's orbit of other objects
But can a "double planet" situation exist with the formal definition of "planet?"

sharinganx12 2 years ago
Sharinganx12,
Agreed. That is totally true. All of our 9 (now 8) planets suround the sun, including Pluto! It doesn't make sense to just make it vanished from the solar system... everyone calls it a "dwarf planet", but it's a planet in my book.

Just because an object has a moon does not automatically classify it as a planet. Venus also doesn't have a moon and it's roughly the side of Earth. If an object is a planet it needs to have done the following:
A planet is any object in orbit around the Sun with a diameter greater than 2000 km, whose shape is stable due to its own gravity, and is dominant in its immediate neighbourhood.
Pluto fails in the last category

I have the answer!!!!!
Pluto isn't a planet because the other planets got jealous. Especially Jupiter. I hate Jupiter.
BRING PLUTO BACK AND KICK JUPITER OUT OF THE SOLAR SYSTEM!!!!!! (xD i'm not crazy, i'm having a sugar rush and a bunch of weird stuff is going through my head)

Uh...
Planets are inanimate objects.
Plus, moving a planet of Jupiter's mass and size would be a really big challenge, considering you would need to move it a couple light years.
Stop having sugar. Talk to a nutritionist.

PLUTO is a planet, but its not considered part of the great 8 anymore. Sedna, Makemake, Eris, and all the other distant objects are usually planets. but stupid picky scientists say that only the great eight are "planets"

Yeah it's not a planet, it's a kuiper belt object, there are many objects like pluto out there, some bigger than pluto like Eris for example. I like the definition dwarf planet. Pluto is really small, smaller than our moon actually.

Pluto IS a planet.
The most reasonable definition of planet is:
'any body which orbits the sun, and which is massive enough to have a moon is a planet'
There is no other reasonable means of defining the term 'planet'. Orbit eccentricity, size, and neighbors don't matter. If it orbits the sun, and is massive enough to (at least potentially) have moons, it is a planet. There is more cause to exclude Mercury as a planet than to do so to Pluto, since Pluto at least has a moon.
PhilosopherEight 2 years ago
Actually, there are quite a few asteroids with moons.
SpitzerJim 2 years ago
Then if we are talking about moons big enough to be truly a moon ( > 100 km diameter, mostly-spherioid shape), then these asteroids are actually planets.
The primary feature of a planet is that it represents a gravitational source that causes nearby objects to orbit IT instead of the sun. It is a hierarchical distinction in the gravity system of our solar system. Any object that is massive enough to have moons, which themselves are massive enough to have sub-moons, is a planet.
PhilosopherEight 2 years ago
The ability of a celestial object to maintain a roughly spheroid shape is called "hydrostatic equilibrium." It's part of the definition of a planet and dwarf planet. The majority of moons in the solar system aren't actually big enough to maintain hydrostatic equilibrium.
SpitzerJim 2 years ago
Yes, but as long as there is at least 1 such moon which maintains hydrostatic equilibrium orbiting a body, that body is a planet. Just because additional smaller moons cannot maintain HE doesn't disqualify the planet classification.
PhilosopherEight 2 years ago
Thank you C3P0.
3089280288 2 years ago
I have to pick on this some. Most objects orbiting the Sun are not in hydrostatic equilibrium either. Some day the IAU needs to define a MAJOR moon.
kpheider 2 years ago
Actually per the IAU definition the primary feature of a planet is the ability to gravitationally clear the orbit of debris. As new debris comes crossing into the zone, it will cleared over a short time scale.

i think the astroid belt was a planet that got crushed because of jupiters gravity pull. my theroy is that there is a planet similar size to jupiter beyond pluto and that pluto and his buddies r just like the astroid belt. lol hard to get this for homework rofl

Zedlav101 2 years ago
Why do people get emotional about such an arbitrary thing as the classification of a heavenly body? Because you have a nostalgic childhood memory of learning 9 planets? What a stupid reason, the model of the solar system has changed and still is. You know, Pluto's orbit is actually littered with objects almost the size of Pluto itself? More complex terms are needed to describe what we know is true and to be opposed to this is to demonstrate your own ignorance.

"Oceania is at war with Eastasia. Oceania has always been at war with Eastasia. Oceania is allied with Eurasia. Oceania has always been allied with Eurasia."
"Pluto is a dwarf planet. Pluto has always been a dwarf planet."
Some of us object to reality being rewritten. The new classification makes no sense, doesn't help clarify future cases of newly-discovered bodies, & is highly arbitrary.
If other similar objects are out there with moons >100km then they are ALL planets.

"these planets are huge, but just too far away for ancient astronomers to see" ...
might be so, but how then did the Sumerians know of their existence and depicted them on cylinders for 'printing' clay tablets?
And why did said Sumerians number the earth (correctly) as counted towards the sun, and not as "third rock from the Sun".
And the Mayan astronomy is no exception, and its mindbogglingly precise calculations has only recently begun to be understood.

Ununennium119 2 years ago
I think scientists should no longer use the term planet, as it's not scientifically useful.
Star's are well defined by properties such as size, mass, composition and luminosity. And stars go into families accordingly. Asteroids are also divided by what they are made off.
For scientific purposes, ditch the term 'planet', but instead make a similar taxonomy for spherical non-star objects. Divide them in families such as jovians, neptunians, terrestrial, plutoid. Instead of muddling with planets.

If pluto intersects neptune's orbit, does that mean there is a small chance of them colliding? That would be cool.
MillionSword 2 years ago
that would be a real scene not to miss! but what are the chances? :p
however, FYI, Triton, the largest moon of neptune, will eventually collide into its neptune, or it will shatter and form an extensive ring of neptune, just to the fact that triton is orbting the opposite way of neptune's spin.
wildalienplanet 2 years ago
no it won't i took about it and asked the same question so no coz while neptune is moving from one direction pluto will take its place for a second while neptune is returning
starfirefan12 2 years ago
Pluto only intersects Neptune's orbit when you look at it in map view. But since Pluto's orbit is on an incline compared to the eight major planets, they're not in any danger of actually hitting. It's like two airplanes, on at 1,000 feet and one at 30,000 feet. From above, they look like they're going to hit, but they're actually nowhere close.
