2. Pluto is one of many dwarf planets in the solar system. That means it meets only the first two criteria of a planet: it orbits the sun (i.e. doesn't orbit another planet like the moon) and is mostly spherical. On top of Pluto, there are four other recognized dwarf planets: Ceres, Eris, Makemake, and Haumea, but scientists believe there may be as many as 100 of them in our Solar System.

3.There are millions of asteroids more than kilometer wide in the asteroid belt between Mars and Jupiter, but half of the mass of the Entire belt is in just three asteroids, Vesta, Pallas, and Hygeia, and one dwarf planet, Ceres.

4. Even though there are over a million asteroids in the asteroid belt that are at least kilometer across, that doesn't actually mean they're that common. The vast majority of objects in the region are the size of pebbles.

5. The asteroid belt between Mars and Jupiter is the most well known, but it's not the only one in the solar system. Starting around the orbit of Neptune and extending for around 20 astronomical units, the Kuiper Belt is massive, ring shaped region of space that likely contains hundreds of thousands of icy objects, leftovers from the formation of the sun and the planets.
