  • An interesting fact for those of you that don't know it. - The "New Horizons" spacecraft (which will reach Pluto in 2015) actually has onboard some of Clyde Tombaugh's ashes. How fitting for the man who discovered Pluto to ride along on our first visit to it.

  • and surely beautiful and maybe lifechanging to have ... walked on it? Good luck with a suit that can withstand it. It's probably much large... or you'd have to stay on the ship. You'd probably need a nuclear thrust just to get across the other planets just to get to pluto on time... THERE AND BACK! I was imagining a nuclear bomb will work like nitros. Surely, that's a thought crossed, but highly dangerous... and what material can withstand such explosion?

  • @mojo9o It's possible to direct a nuclear blast with conventional materials. The thing is that nuclear explosions are highly inefficient.

  • @mojo9o I believe that's exactly what Project Orion was about, using nuclear thrust to gain high speeds. But later on after a debate, it got banned since it spread radioactivity in space :/

  • @TheSteady0 Space is already radioactive, a mere nuclear blast won't do any harm at all...

  • @TheSteady0 You are completely correct except for that they didn't want radioactive matter in space because they didn't want it exploding and raining radioactive debris into the atmosphere. They don't care if the radioactivity is only spread into space.

  • It's okay Pluto I still love you!!! <3

  • If I remember right, if Pluto's size classified it as a planet, there would be 14 planets in our solar system. So; eight without it, or 14 with it. Kinda ruins the sentence they tried to teach to people for remembering the planets and their order - "My Very Easy Method Just Speeds Up Naming *(planets) removed* "

  • I've wondered about this since I first read about the Kuiper belt: Is there enough energy in the masses in the Kuiper belt to cause then to accrete eventually into a planet; if not, how much energy would be required to kickstart an accretion process and what, if anything, could cause that to happen?

  • 3:10 i think that the moon of pluto was actually given its name by the wife's name of astronomer that discovered it.

  • Why you hating on pluto biatch?

  • It's ok Pluto, I'm not a planet either

  • is Pluto a plantiod form older solar system?

  • 3:01 The Roman and greek gods are originated at ancient Greece so maybe its more correct to call it Greek god and not Roman. but they shared the same ,give or take, gods. to be more corect you can say: named after the Greek and Roman god Pluto that in Latin we wrote it Pluto and in Greek has a different writing and spelling. Named after the Latin word for the greco-roman god pluto. but the theology is originated in greece.

  • Dear scientists of Earth, your mom though I was big enough.

    Sincerely Pluto

  • The Greek story is that Dionysis went East to discover wine, possibly to Shrraz.

  • Pluto is a hipster.

  • Pluto demoted this is clearly a case of social injustice.

  • PLUTO is not the roman god of the underworld but the greek god of the underwold,charon was the boatman of styx river and his job was to transport with his boat the dead to the underworld

  • @nektaga Sorry, but Pluto was the roman God of the Underworld. The Greek's God was called Hadès.

  • @Elvenheim PLUTO(DIS, this is the roman name);one of the twelve olympian gods,sun of KRONOS(saturn) and REA,brother of DIAS(jupiter) and POSEIDON(neptune).God of the dead and their shadows.he was the kidnaper of PERSEFONY,(daughter of DHMHTRA).he also had the following names;HADES(ΑΔΗΣ),HEDONEYS(ΑΙΔ­ΩΝΕΥΣ),SCOTIOS(ΣΚΟΤΙΟΣ),PERIKL­YMENOS(ΠΕΡΙΚΛΥΜΕΝΟΣ),SARAPIS(Σ­ΑΡΑΠΗΣ),EYVOULES(ΕΥΒΟΥΛΕΥΣ)HIS­ODAITE(ΙΣΟΔΑΙΤΗΣ).the name HADES wasn't only one of the names of PLUTO but one of the names for the underworld

  • She's very nice looking. Naturally.

  • Very nice series but again a correction :

    Pluto was named after the Greek god "Πλούτωνας" (Plutonas) who is another name of the god Hades; god of the underworld.

    And all Planetary names ,expect 1-2 moons of Uranus, come from Greek mythology not Roman

  • @zealotkill

    Jupiter, Saturn, Mercurius, Venus and Neptune are all names of Roman Gods. Just Uranus is Greek.

  • @sbrenn

    m8 get your facts staight ... i do know my own mythology and my own 12 ancient olympic gods. google some more ... Romans and the Roman empire adopted the greek gods as the roman empire conquered the Greeks in 146 bc.

    The name u mentioned above are all names of Greek gods as changes by Romans.

    For ex, Jupiter is Zeus ,Venus is Afrodite ,Mercury is Hermis and Neptun is Posidon .

    Wiki some more :)

  • @zealotkill

    That's all fine and good, but Jupiter is not called Zeus. Venus is not called Aphrodite etc.

    All Gods have predecessors, even Christian ones.

    I think you would find that even Zeus had a Sumerian daddy...

    But let's leave it at "They chose the Roman names" for the planets. You can't argue that :)

  • @sbrenn

    ok lets leave it to that. All i was saying is that the the Greek name is the name heavily remember by the public as the origin of the planetary names .

    I aint saying that Greek gods dont have predecessors ...course they do ... its in human nature to do such things.

    Cheers !

  • I just watched the entire planets playlist, an hour give or take a few minutes, it's 2:40AM and i'm still intrigued. Brilliant little series.

  • Isn't it "shar-on"?

  • for me this works fine...

    its totally logical and since we are still discovering other pluto-like objects in the kuiper belt, it's necessary to rethink pluto's "status", else we would have about 15 planets or so (dunno the exact number of already discovered pluto-like objects)

    so pluto is now a dwarf planet along with those other objects and, funny enough, the biggest asteriod in our solarsystem called ceres...

  • in 2005 astronomers discovered another celestial body even farther out than pluto that is even bigger than pluto - they called it eris.

    since that conference of the IAU, celestial bodies need to meet 3 requirements to be called planets:

    1. the body must orbit a star (and mustn't be a star or moon)

    2. the body must have enough mass for gravity to form it roughly spherical

    3. the body must have cleared its orbit of any other objects

    for pluto the first 2 apply, the third one not.

  • Pluto will always be a Planet to me, I'm sorry but it has moons...ITS A PLANET.

  • @iSynOSX What happens when the moon is almost the same size as the planet? Which is the moon? And anyway, if you took every object out there with the characteristics of Pluto and called it a planet, we'd have hundreds or thousands of things called planets with no separate classification for the obviously different things that are actually planets.

  • @Ormaaj let me use your own words to answer that, "Almost the same size" well if it is ALMOST the same size that would mean that it is still SMALLER. Which one is the planet and which is the moon? refer to previous answer. and I was unaware that we had masses orbiting the same star we do that have moons orbiting around it, I always assumed that was called a PLANET.

  • @iSynOSX

    There are also smaller objects that have moons orbiting them. There is one asteroid (I had to look up the name), it's called Ida and its moon is called Dactyl. The length of Ida is only about 54 km. The question is, should we consider that one a planet too because it has a moon? I guess it's sort of a matter of preference how to classify things. But there are other reasons why astronomers choose to classify things as dwarf planets, etc.

  • @iSynOSX

    The Dwarf Planets Eris and Haumea both have moons. Are they planets too? Eris is even bigger than Pluto.

  • So what about the asteroids with moons, like Ida?

  • Tombaugh was an amateur astronomer and the professionals have never gotten over it.

  • Scientists are hot...

  • Oh no! This means Drake's equation must be revised!

    The estimated average of planets per system should shift from 4.5, to 4.

    By demoting Pluto to a Kuiper belt object... you have exterminated several advanced hypothetical sentient civilizations in our Milky Way! You monsters!

  • @L00NGB00W That may need to happen but dude... In reality... Pluto IS part of the Kuiper belt.

  • @L00NGB00W We don't base that part of the equation on how many planets are in our solar system but how many planets are in any given solar system in our galaxy. Changing how many planets are in our solar system will not change the average for the entire galaxy.

  • I'd pay her to lecture to me at night while I fall asleep.

  • Sciece should stop picking on Pluto just because it is smaller.

    It makes a difference to Plutonians who live there LOL.

    Their are other 'wonky' planets.

  • she looks jewish

  • @TheArmo1 no, she looks irish, maybe italian, some polish, or perhaps czech with some gypsy ancestory and an armenian grandmother on her father's side...

  • @TheArmo1 agreed.

  • I like this woman very much. But I don"t like Pluto as he brought mostly troubles in my life.

  • PL doesn't stand for Pluto, neither does it stand for Percival Lowell. It stands for PLANET........you bastards.......you bastards.

  • It is just binary planet, like billions binary suns in the universe. There is no need enforcing exceptions when there are already established rules.

    It is Pluto Charon binary planet. Get over it.

  • @th3dig1tal0n3

    The real problem is that there are lot of other things like Pluto out there, some larger than Pluto.

    Unless you wanna say we have dozens of planets, you have to say we have 8. Since these small outer bodies, like Pluto, all have the same sort of quirks as Pluto, it makes more sense to just classify them differently and group Pluto into that new classification.

  • @InB4Desu Pluto is strange in many ways, but classifying it the wrong way is bad. It's current classification is simply wrong. It's orbit is strange, but in the orbital way it does not belong in Kupier belt. There might be a lot more objects like Pluto in the Kupier belt, but they are in the belt, the Pluto is not.

    Also, debating and voting is not scientific method. The "Get over it" part was from BBC's documentary watch?v=90TWpYkMj0I

  • @th3dig1tal0n3

    I'll remind you that prior to this debate 'planet' had almost no scientific meaning.

  • @th3dig1tal0n3: Watch out for those windmill blades - they will just swoop down and clout you while you're trying to get it to joust you.

  • @puncheex Blades of authority are too slow for me. I'll just sit underneath, pull one rock at the time and throw at them.

  • something about this girl i find extremely attractive.

  • she is kinda skinny

    she is smart

    what else do you want?

    i think she has a "wild" beauty that bonds it all together.

    i would go as far as saying she is sexy

    p.s

    please don't shoot me i know this is a video about science but....i can't help myself

    lol

  • lol i'm not asking you to agree with me.  ... my statement stands.

  • yes...and you are absolutely right

  • Good job :D

    besides, 8 is better than 9 :P

  • how come nothings ever got hit by dark matter theres alot out there

  • @Rohan11221 coz dark matter does not react with anything .. could possibly be neutrinos ..

  • @rhn94

    Dark matter DOES react with things. It's the gravitational effects of dark matter that tells us it must exist.

  • @InB4Desu i meant a physical reaction ..

  • @Rohan11221: 'cause dark metter doesn't hot anything. All it can do is pull.

  • I think plutos feelings are hurt for sure.

  • i love her teeth+smile :D 5/5 also very informative ^^

  • When did Horizon launch?

  • Launched in January of 2006, and will reach Pluto in July of 2015. So it's about a third the way there.

  • I can't (well actually I can) believe it takes so long to get that far! Do you know if it's making any stops along the way?

  • I don't think so. It passed fairly close to Jupiter and photographed the planet and some of its moons. It also took pictures of a couple asteroids.

  • Comment removed

  • I thought I read somewhere that it got reclassified again. As a Plutoid! :D Which I think it the better idea, if it can't be a planet then it might as well become the first of entirely new classification. So all those Kuiper (sp?) belt objects should now be called Plutoids.

  • @celticarchie: it's official designation is as a dwarf planet, a member of the Kuiper group of objects.

  • Gewyne, I completely agree with you! In my mind there will always be nine planets, and I will teach my children so.

    ps. Is there a "keep Pluto a planet" movement?

  • Only among really sentimental scientists.

  • @Desmaad And Kansans, since our own Clyde Tombaugh discovered it. Now our fame falls to the dubious collection of; the Largest Ball of String, Largest Hand-Dug Well or the 2,000 lb. Prairie Dog. Of course you could throw Brown v. Board of Education, but that would portray this as a thinking person's state. So, as if to just jam it in our faces, the word comes from on high "NO CLYDE, YOU IDIOT, there's lots of your Pluto's (dwarf planets) like the one you've found out here. Stupid Kansan Fail.

  • Shame. 'Intelligent' people arguing about the origins of etruscans without actually researching it first, it seems, and then bashing each other. Fail at debates much? *sigh*

    Last time I checked, this is a video about astronomy, not anthropology...

  • @whaaful: Not really. Definitions are important in science, and it was time that the AAU defined what a planet was, particularly as there are known Kuiper objects larger than Pluto. Sentimentality be damned.

  • Romans and greeks do not have the same origins. Greeks come from Tribes Such as Dorians Ionians And Corinthians that descented from north europe(indo-european) and Romans come from Etrusks another different "tribe" that inhabited north italy. Later on when the greek civilization flourished and commerce expanded greeks brought their worshipping whereever they went. Thats how etrusks and later on romans were influenced.

  • youre a goddamned idiot then krotidas, get an education before you go saying that latin and greek people dont share a common origin. do you know a damn thing about indo-europeans at all? etruscans were an isolated culture and spoke a language isolate, they were in no way indo-european, which is why to this day their language has never been fully deciphered. go and learn your history you fool before you make yourself look more like an idiot than you already have.

  • Ok man whatever...

    BUT! General conclusion= Greeks werent the same as Romans.

    Ty and GF!!!

  • i never said that greeks were the same as romans, i said they shared a common origin, both culturally and genetically, and therefore had the same gods with different names because of this shared origin. just dont go saying that romans stole greek gods, because while it is true that they adopted a lot of the mythology that evolved in greek religion over time concering their commonly shared gods, they did not steal gods from greeks or celts or persians or germans, they all shared the same gods.

  • DID I SAY THAT ROMANS STOLE THE GODS FROM GREEKS?? THEY JUST WERE INFLUENCED BY THEM. pffff

  • calm down lady, just admit i owned your ass and proved you wrong on everything you said...and no, macedonia is not greek...

  • pff roman gods. These are greek gods that were worshipped later by the romans.

    Pluto was the ruler of the underworld.

  • *stolen by

  • actually the romans and greeks worshipped the same gods since they are both indo-european, and over time as the different tribes migrated around their language changed along with culture and mythology...jupiter = zeus pater = sky father

  • Ehhh.. i know :) i am Greek

  • well then dont say that these are greek gods that were later worshipped by the romans, since the romans worshipped the same gods as the greeks did but with different names, ie latin instead of greek names, and these gods are also the same that are still worshipped in hinduism, etc...just makes you look like a dick mate

  • Romans=Later civilization than the greeks.

    Greek Goods=Later worshipped by the romans.

    Simple Logic.

  • actually romans were worshipping the same gods as the greeks were before both of them were civilizations, back when they were fierce nomadic warriors of the southern russian steppe and over the course of a number of migrations the original indo-european culture diversified and spread over most of europe, central asia, south asia, and asia minor. the greek gods and the roman gods were the same just as the roman gods were the same as the aryan gods etc since they were the same peoples originally

  • I am not trying to say that these gods were different but what i am trying to say that they were originally worshipped by the greeks.

  • If anyone told me they thought Pluto was named for the dog, I would punch them in the face.

  • Isn't Pluto just an exceptionally large comet?

  • I think that the range of its orbit, distance from the sun, and composition prevents it from being called a comet.

  • It's the fact that it is massive enough to be rounded by its own gravity and is not a satellite, but has not cleared its neighboring region of planetesimals.

  • So before you complain about your demotion, remember; Pluto.

  • Thanks bird. youre fit. ANYWAY>>> it suggests teh idea that rather than stravelling to other stars to find other planets, us humans could build a new planet abit further than the earth my sending many large kuiper bodies closer to the sun, byu choosing ones with water and the right chemicals.

    okay ill get on the case. who has some jetpacks.

  • stupids. of course it doesnt matter if its a planet, it is half planet half not. like is a grasshopper a hopping grass , no. so what

  • Pluto will always be a planet to me:-(

    Sniff!

  • quit living in the past man!!

  • Make accurate videos first.

  • @flutist218: Go watch "The Pluto Files" on the NOVA site. Neil Tyson started the debate by leaving Pluto out of a display of the planets, causing a furor among school kids. In a clever production piece Neil drives to Streator, IL where Clyde Tombaugh grew up, and goes into the local barber shop to get a shave. He asks how the locals feel about Pluto as the barber has the straight razor to his neck, and they start mumbling about what they'll do when they catch that city guy who dissed Clyde...

  • I wonder... if pluto and neptune's orbit intersects... can they collide in the future?

  • Nope, Their orbits actually don't intersect but instead pluto's orbit is inclined away from the plane containing Neptune's orbit. They only look as if they intersect if you look at the plane from one side of it.

  • ah.. yes, I found a graph showing it. Thx! =o)

  • Comment removed

  • @puncheex yeah! Thx!

  • Oh.. I was outside of that observatory yesterday.

  • Really, I could very possibly listen to her for hours.

  • Youre not the only one ;)

  • Let's make a fan club of her...whoever she is ;) I could listen to her and look at hear for hours too!

  • Me too, It must be a sign of my age that I find SMART women so freakin HOT. Is that wrong?

  • so Sailor Pluto from Sailor Moon is no longer a "Sailor" anymore huh? =P

  • plutoooooo

  • I concur with Niel DeGrasse Tyson, Pluto had it coming.

  • Yeah, I agree. There's also a great video on YouTube from AtGoogleTalks of Neil deGrasse Tyson talking about Pluto and other comic quandaries. Well worth the watch...

  • This lady is really good looking.

  • my science teacher said that taking photos of it would be like trying to read the brand name on a golf ball from 30 miles away with a human eye

  • ...in fact other objects similar to Pluto were discovered using very large and dense CCD sensors, you can think of it as a Gigapixel camera!

  • I love these vids, i learnt lots about pluto then like the orbit :)

  • so the song in Hebrew is right

    "שבעה כוכבי לכת צצים על כל גבעה"

    "Seven planets seen over all the hills"

  • Seven? There are eight planets.

  • earth is excluded as you're on it

  • Now, I feel stupid :(

  • did she just... diss pluto? BLASPHEMY

  • Hello,

    I love your videos, keep on trucking!

  • great video
