Up until 2006, Pluto was considered a planet. We now know that Pluto is in fact a dwarf planet. Pluto is not only considerably smaller than other planets but it orbits the sun with asteroids and comets rather than the planets.
Pluto is about two-thirds the size of Earths moon and has a rocky core encapsulated by an icy mantle. Pluto’s surface is made up mostly of methane and nitrogen.
Pluto has a large moon, named Charon and its orbit takes about four and a half Earth days. Charon hovers over the same spot on Pluto causing tidal locking.
Pluto is named after the Roman God of the underworld.
