6 FAQs about [Solar system including pluto]

Is Pluto a planet?

Pluto is a very active ice world that's covered in glaciers, mountains of ice water, icy dunes and possibly even cryovolcanoes that erupt icy lava made of water, methane or ammonia. Related: Why isn't Pluto a planet anymore? In 2016, researchers proposed the possible existence of a ninth planet, for now, dubbed "Planet Nine" or Planet X.

How did Pluto become a dwarf planet?

The dwarf planet's entire moon system is believed to have formed by a collision between Pluto and another planet-sized body early in the history of the solar system. The smashup flung material into orbit around Pluto, which then coalesced into the family of satellites now seen.

Is Pluto a double planet?

Pluto is orbited by five known moons, the largest of which is Charon. Charon is about half the size of Pluto itself, making it the largest satellite relative to the planet it orbits in our solar system. Pluto and Charon are often referred to as a "double planet."
