Back in MY day, we had 9 Planets!

[Jak595]

We won't. Humans will never leave planet Earth. :c

in mah words they will :D
hope we envolve fast so we can really go to another galaxys and discover new planets :D

At the top of the picture, you can see how Pluto's orbit interferes into Neptune's orbit.

Oh god huge interplanetair collision in 12 billion years!
Wait sun burns out in 5.

If it has a gravatational pull, I'll consider it a planet.

The sun is a planet?

All these idiot scientists
 

have fun in the stone age then

"Dwarf Planet"? I always heard it being called a moon.

Anyways, Pluto IS a planet and has been ever since. It's just small, but doesn't mean it's not a planet.

[Jak595]

The sun is a planet?

No. the sun is a atomic exploding bomb.
it will destroy everything and maybe create a black hole.
it will happen in billions or millions of years! while the sun is a giant red.

So everything is a planet from a soda bottle to an elephant to a black hole.
That's nice.

No, it's not a planet. Why? Because we can't call every loving star-orbiting satellite a planet, we established rules for planet status, and Pluto doesn't fit. It's a dwarf planet, get over it.

PS if we included Pluto as a planet, then we'd have 13 planets. Eris, Ceres, Haumea, and Makemake are all Dwarf Planets that orbit the sun.

Pluto is too small to be a true planet, yet it is too big to be a moon. So it's a dwarf planet.

Not all stars become a black hole.

No.

The definition of planet set in 2006 by the International Astronomical Union (IAU) states that in the Solar System a planet is a celestial body that:
is in orbit around the Sun,
has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and
has "cleared the neighbourhood" around its orbit.

i said maybe, not all

You are a planet.

Brilliantly said!

We should have 13 planets in our solar system.

[carolcat]

Ooh, fun! Now I can have planetary collisions with my friends and then go tell NASA and have people freak out! HAHAHAAA

 No. That sounds dumb :/
