small.
Earth is the biggest of the terrestrial or rocky planets, but smaller than any of the gas giants.
the relative size of the other planet is Jupiter, Saturn and Uranus.
Pluto is smaller in size compared to the other planets in our solar system. It is classified as a dwarf planet, with a diameter that is smaller than Earth's moon. Among the eight recognized planets, Pluto ranks the smallest.
Dwarf planets are not a special type of planet. A small planet is later classified a dwarf planet. The only characteristic that makes it a dwarf planet is the size. Your question should be why are some planets small?
Yes, tiny planets are still called planets as long as they meet the criteria of orbiting a star, being spherical in shape, and clearing their orbit of other debris. Size does not define whether an object is considered a planet.

Compared to some other planets in the same galaxy, yes; it is actually fractions of the size of other planets in this galaxy
Pluto is about half the size of Mercury, which is the smallest "true" planet.
it is small, even smaller than our moon
The Earth is a planet if that is what you are asking. It is a planet in our solar system. However compared to the the relative size of other planets in the solar system earth is quite an average size.
It is the third largest planet in our Solar system.
Very small of the accurate anus, but reffering to the planet, it is the third largest planet.
