Sun (Proper name: Sol) Mercury Venus Earth [u][b]Mars[/u][/b] Asteroid Belt- contains Ceres (Dwarf Planet) Jupiter Saturn Uranus Neptune [u]Kuiper Belt[/u] (contains these dwarf planets, and is beyond the orbit of Neptune) Pluto (dwarf Planet) Sedna (Dwarf Planet) Eris (Dwarf Planet) Haumea (Dwarf Planet) Makemake (Dwarf Planet) As you can see, OP; Mars is not the farthest planet, nor will it be the coldest. While Mars is in the "green zone" of Sol (necessary to have enough heat to support liquid water and thus life), it is on the outer most edge of that same "green zone".

  • I always heard it pronounced Kiper belt, but I may be wrong or thinking of something else

  • It is pronounced that way, but spelled with a "U".

  • Thank you for this information. I found reading your response to be stimulating, I did not no there are so many dwarf planets now! Cool stuff.

  • Isn't Pluto a planet again?

  • Nope. Still fails one of the three requirement to meet planetary classification. To classify as a full planet, a body must: - Be an object which independently orbits a star (cannot be a moon of another body) - It must have enough Mass that it's own gravity pulls the body into a rough spherical shape - It must be large enough in size that it "dominates" its orbit (i.e. it must be the largest object in its orbit trajectory and therefore have enough Mass to "clear out" other bodies in its same orbit [either by absorbing then into it's own Mass, eject other bodies from its orbital trajectory, or capture other bodies as moons]). Pluto (and the other Dwarf Planets) only fulfill the first two requirements.

  • Isn't Pluto a Moon? So does it have a solid surface?

  • No, but Pluto does have it's own moon.

  • Pluto isn't a moon, but it does have a solid surface, you could think of Pluto as being an oversized cluster of dirt and ice.

  • Yeah, I read that. I didn't place it in my list because they have yet to be proven; much less seen and given a numerical designation until confirmation and naming. According to this new theory, the two hypothetical planets could also not only be that far out, but their orbits might be perpendicular to the "regular" orbital plane. If that theory is correct, it would explain much on why they haven't been discovered already. Exciting stuff in astronomy and astrophysics!

  • Mars is not in the Habitable Zone actually.. I wrote a paper solely on the inhabitability of Mars... Only about 1/100 of it's orbit is anywhere even close to the habitable zone

  • Last I knew, it was riding that edge. With new information, they may have changed the distance that the habitable zone stretches. I could very well be wrong and that Mars is outside of it. Still, even if I am wrongl Mars will not be the desolate snowy playground that OP thinks it should be. lol Thank you for the clarification and new information. :)

  • Mars is about .02AU out of the habitable zone, but that is also dependent on the source I used. So me coming at you guns blazing was a little it unnecessary but nonetheless it is JUST outside that zone :P

  • Omfg I'm old and dumb. How long ago did Pluto stop being recognized as a planet?

  • There are also more Dwarf Planets in the Sol system, but they are waiting on confirmation of size/mass to prove that they aren't just overly large asteroids or comets, and so far they have only numerical designations from the International Astronomy Association. Once confirmed, then they will get proper names.
