What planet is most like Earth in our solar system?
Venus and Mars are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth.
Is an Earth like planet outside of our solar system?
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917, but was not recognized as such. About 1 in 5 Sun-like stars have an “Earth-sized” planet in the habitable zone.
