Earths atmospheric size and composition is unique among all of the planets.
the earths orbit because the earths orbit is the size of earth + the size of the moon
Venus.
Pluto would be the best answer, but Pluto is only a dwarf planet. Also its largest moon, Charon, is still not as big as Pluto itself.
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Its also the planet that gets closest to Earth, the next one orbiting inside earths orbit.
There is no planet that has the same size moon as the planet. This is only possible if Pluto was still a planet.
In size and mass it is enormous compared to it's parent planet - The Earth.
Their is no planet the same size as Pluto, Mercury is slightly bigger than Pluto. As for other objects in the solar system, the dwarf planet Eris and Neptune's moon Triton are close in size to Pluto.
Charon.
Venus is closest to earths planet size.
Venus, because they're about the same size
It is a moon of the dwarf planet Pluto. They are so nearly the same size it could almost be called a double planet system
Pluto
Because of the Earths rotation, Happy astronomy! :)
