We seriously lucked in. So many things about Earth are Just Right for habitation that in even one of them were changed a little bit, we'd all have to leave (if we could).
Here are just some:
1. Earth's Sun is the kind (about 4% of the stars are) that a) lives long enough for life to get underway and prosper and b) can have planets that aren't tidally locked, lilke Mercury.
2. Earth is just far enough away from a Sun of the right size that it can have lots of liquid water (not ice, not steam), plus some of both (ice & steam, or clouds).
3. Earth has a magnetic field that helps shield it from cosmic radiation.
4. Earth has a big "friend" in the planet Jupiter, that scoops up a lot of debris that might otherwise hit it.
5. Earth has a big Moon, which helps to stablize it.
6. Earth and the Sun live in a nice "suburban" part of the Galaxy, where there aren't too many stars to jerk us around with their gravities, but close enough in that we had instellar material to make a Sun and a few planets.
7. Earth is big enough to hold on to its atmosphere (unlike little Mars, which lost its long ago), but not so big that its atmosphere would crush things, like Juipiter, Saturn, Uranus and Neptune do.
8. Earth isn't so tectonically active that it has a runaway greenhouse effect like Venus.
9. Earth's Sun is a Population I star, which has some heavier elements good for making complex things, like plants and animals. We have some long-gone supernovas to thank for making these elements for us, because our Sun is too small to make them itself.
It probably wouldn't be habitable, if the Earth's axial "tilt" were 90 degrees.
The duration of Planet Earth - TV series - is 3000.0 seconds.
Earth. Scientist were almost about to call earth "Water" instead. The earth is the watery planet because it is has 2/3 of the ratio water/land. Hoped that Helped!!

earth..The most habitable planet in the Solar System is Earth. As of June 2014, Earth is the only planet that has sustained known living things.
earth
mars
i have no idea ok im done
mars
Temperature is one factor that makes an environment habitable for a species.If Earth were destroyed, humans would have to locate another habitable planet.
You don't need to - it is already extremely habitable although some people seem intent to reverse that fact,
Earth is habitable because of our natural resources. Water, and land capable of growing food. Our atmosphere is perfect for life. The sun is the perfect distance away.
No. The only planet available to support life is planet earth. Pluto is on average at least -50 degrees.
If We are talking about planets, That planet need to me in what they called Habitable Zone What Is a Habitable Zone A Habitable Zone is the distance between a Star (Sun) and a planet, in which a planet like Earth can maintain liquid (water) and a distance which can allow water not to freeze or evaporates.
The habitable zone is defined as the region in a star centered orbit where an Earth like planet can maintain liquid water on its surface.
Earth is the most habitable planet in the solar system, which is why there is so much life on it. As far as we know, no other planet has life on it. Mars could possibly support human life, with supports to help them.
