@SuperSpaceMaster. The planets that have satellites are called mother planets. The satellites are just that: satellites. It would be highly unlikely for a moon to orbit another moon that is orbiting a planet. Also, that moon would have to have an extreme gravitational pull.

what I wouldn't give for the 9:29 view. <3

how is O_o a top comment? o_O

[The1Skinsfan]

Cool.

[yourfunnyhehe1212]

@hlubgtiaproduction Remember that to support life you need the elements hydrogen, oxygen, sodium.. etc, so maybe you are correct, like you said, no one knows.

[hlubtiagproduction]

CONTINUES.

What if billions of years ago, that star used to be smaller and have more planets orbiting closer than the gas giant planet does today. And because of the star get older and grow bigger as time goes by. It swallow all the planets that orbiting close to the star. So, what NASA discover about the gas giant planet why it orbiting too close to the star are the aftermath.

[hlubtiagproduction]

Scientist said in the next several billion years, our sun will grow into a giant star. If that is truth then that mean our sun used to be smaller compare to now. And also that mean millions or billions of years ago. Mercury was habitable of sustaining life just like earth does today. As the sun get older and grow bigger, Mercury died out. Then Venus become habitable. That means, four of the rocky planet have their turn of becoming habitable as the sun get older and growing.

[hlubtiagproduction]

That just my theory. It might or might not be truth but no one knows. Also in this video they show that they found hot jupiter or other gas giant planet orbiting close to the star. What if my theory is correct. What if billions of years ago, that star used to be smaller and have more planets orbiting closer than the gas giant planet does today.

oh that osirus place seems to be the perfect place to work on my tan.

[weedazza21]

1:08 no i havent LOL

[SuperSpaceMaster]

I wonder if the moon of a large gas giant could have a moon of its own? Like a plant 5 times the mass of Jupiter, with a moon between the sizes of Mars and Venus, and that moon having a moon with a diameter of a few hundred km?

[jdaniels161]

I'm not going to lie it would be nice if earth could swing pass jupiter. imaging around winter we see a gas giant in the sky during the day, and at night it lights up the sky. it would be like pandora

[Crunox]

I hope we never go to mars, other than to study it. I hope we won't live on it and fuck that planet up too... If earth dies, we got what we deserved.

[NotSooNoobish]

@Crunox fuck mars up? there's nothing there as far as we know

[Crunox]

@NotSooNoobish I've heard their are " plans' to terraform mars to a habbitable planet. That's why i said 'i hope they never do' because we're already fucking up this planet.

[siewmj1]

@Crunox we will learn from our mistakes, sapient intelligent will enable us not to repeat the same mistake twice.

[frosted77]

they came for bio fuel .......did they have carbonne taxe in space ?? hahaha xD

[danielsolomos]

LOL "GLOBAL FRYING" EPIC WIN

[TheSupreme676]

NatGeo should make a "Spore like" game.Would be epic

[nirsh1000]

o_O Global frying..!

[charmeurify]

i wish mars would be safe now and people can live there!! and i will buy the mt olympus.. and consider myself a god/godess.. LOL

[4squaredby4times4]

Mars was once an Earth-like planet before it died. According to some theories.

[robertas2391]

@4squaredby4times4 how do u know ?

[sandcut1]

@4squaredby4times4 And it might happen again as our sun heats up and the habitable zone migrates outward.

[MrFootballstar98]

@4squaredby4times4

Your right same with pluto mars was to hot and pluto to cold so all life died on it but not many people know about pluto

[4squaredby4times4]

@MrFootballstar98 I'm assuming you're being sarcastic. Wrong form of the word you're. And it's too cold, not to cold. Stop being sarcastic. The atmosphere on Mars is the closest in the solar system to the atmosphere on Earth. There is also evidence of shore lines on its surface. Leading many scientists to believe that it was an Earth-like planet. Keep an open mind. Mars was too hot? What? Mars is cold silly.

[MrFootballstar98]

@4squaredby4times4

my bad i meant pluto was to cold not mars pluto used to contain life but everything died on it the hubbletelescope found that out a couple of days ago
