Have you ever wondered how big Pluto is compared to the Earth or even to other planets in the solar system? Pluto is known as a dwarf planet, which means it’s a lot smaller than planets like Earth, Mars, or Jupiter. To give you an idea of just how small Pluto is, let’s do a size comparison.
Not only is Pluto smaller than most planets, but it’s also located much farther away from the Sun. Pluto’s orbit ranges from 30 to 49 astronomical units (AU) from the Sun. An astronomical unit is the average distance between the Earth and the Sun, which is about 93 million miles or 150 million kilometers.
Pluto may be small, but it’s made of some pretty interesting stuff. Like other objects in the Kuiper belt, Pluto is primarily made of ice and rock.
