Quizplus · Accepted Answer

Pluto's density is most similar to the moons of the jovian planets. This is because Pluto is a dwarf planet located in the Kuiper Belt, which is more similar in composition to the icy moons of the gas giants than to the rocky terrestrial planets or the gas giants themselves. Pluto's density is similar to moons of the jovian planets, which are mostly made of water ice and rock. This suggests that Pluto may have been a captured moon of a giant planet, rather than a true planet formed in place.
