The CoRoT-7b is a newly discovered planet that is very similar to the earth because it has a very similar mass and radius. CoRoT-7b is 500 light years away from the earth. This planet also has a similar parent star to the sun, but the planet is much closer than the earth, which makes its peak temperature much hotter than the earths. It is closer to its star than Mercury is to the sun. This planet orbits its star in just 20 hours. Further research will likely show that this is one of the first rocky planets to be discovered outside of our solar system.
