mars is the closest to living, atmosphere, polar caps. Even the temperature can reach the same as our earth.
the temperature goes from -143 (something like that) to +17
the atmosphere is 95 percent carbon dioxide with traces of nitrogen, argon, oxygen, carbon monoxide, neon, krypto, xenon, and water vapor

No planet in this solar system, not even Mars, is close enough to Earth for us to live on it...at least, not without a lot of equipment to make it safe. Mars's atmosphere is far too thin for us to survive in it, and even if its atmospheric pressure were the same as Earth's at sea level, it's still mostly CO2 and very little free oxygen. Furthermore, the surface of Mars is far below the freezing temperature of water. If we were to establish a permanent base on Mars now, it would have to be a completely enclosed structure with machines working constantly to keep the pressure, O2 level, and temperature within survivable limits for human beings.
Of course, the problems associated with living on Mars are NOTHING compared to what we'd face on Venus. Instead of having a thin, cold atmosphere, Venus's surface pressure is about 90 times ours and there is a constant temperature of 750 K (477ºC or 891ºF). Again, the atmosphere on Venus is mostly CO2, so it wouldn't be breathable even if the crushing pressure and extreme temperature weren't problems.
Mercury has no atmosphere worth mentioning, nor does the Moon. Jupiter, Saturn, Uranus, and Neptune are all gas giants...if they HAVE any solid rock to stand on, it's buried beneath thousands of kilometers of high-density gases and liquids. There really isn't any place in the solar system that could support human life other than the Earth.

We really don't know of any planet close enough to ours for us to live on. The previous answerer said Mars, but I don't think it is close enough to Earth. The surface pressure on Mars, on average, is less than one percent than that of Earth. The gravity is low, and it has no magnetosphere. That means that there would be no protection for us from all the UV radiation coming from the Sun and elsewhere in space. And it's atmosphere is nothing like ours. We have about 70% Nitrogen and 21% Oxygen, with about 0.04% Carbon Dioxide. Mars' atmosphere is 95% Carbon Dioxide and 3% Nitrogen, with trace amounts of Oxygen. And it's poles is not frozen water like ours. Rather, it is frozen Carbon Dioxide (dry ice). So while there is talk of having manned missions to Mars and you see people living on it in movies, I doubt we'll be living and raising families on Mars anytime soon.

Their is a planet just like earth but a bit bigger and it might surport life and it was dicsovered this year.
People call this planet New Earth and you should watch some news sometime they have intresting things about discovering new planets.

None. Although more research needs to be conducted of some moons of Jupiter and Saturn.

None that we know about. Maybe some undiscovered planet will be, but we don't know about it yet.

So far Mars. It has polar ice caps like earth and its atmosphere is closest to ours

In our solar system, none.
