No planet is exactly the size of Earth. Venus is close to Earth's size but slightly smaller.
Mercury, Mars, and Venus are all smaller than Earth.
Venus is only slightly smaller than Earth.
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
No planet! However, Venus has no moons and is not much smaller than Earth.
No planet is the exact same size as the Earth but Venus is very close (it is just a little bit smaller) Mars is even smaller. See Link for a tour of planets and stars arranged by size.
Not exactly. Venus is the closest to Earth in terms of size comparison, it is a little smaller.
Pluto was a planet but they didnt want it to be a planet anymore because it was so tiny. But Pluto is alot smaller than earth.
Venus is most nearly in size to the Earth, just slightly smaller.
A planet called Kepler 186f, in the constellation Cygnus, is the same size as the Earth and it is similar to Earth in looking to. Venus is only slightly smaller than Earth and is the closest in size to it in our solar system.
Venus, it is slightly smaller, and much hotter
The planet Venus is closest in size and mass to planet Earth. It is only slightly smaller and roughly four-fifths of Earth's mass; for this reason it is sometimes referred to as Earth's twin or sister planet.
