PLUTO

pluto_108865s

Pluto was discovered in 1930. It follows a strange, strongly elliptical and tilted orbit compared to the other planets.

At its furthest point it is 49 times as far from the Sun as Earth. At its closest it is nearer to the Sun than Neptune. Pluto has a satellite, Charon, whose diameter is 55% the size of Pluto, making the pair almost a double planet.
