Triton, the largest moon of Neptune. Because Triton has a retrograde orbit (opposite that of it's planet), it was likely captured by Neptune's gravitational pull from the Kuiper Belt. It's about the same size and has a very similar makeup to Pluto, another Kuiper Belt object. Triton's orbit is slowly shrinking, and it is expected that in about 3.6 billion years, it will either collide with Neptune or be destroyed, forming a Saturn-like ring system.
This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach.
Hyperion is a moon of Saturn which has a size of 360 x 270 x 205 km. It is the largest irregular object of the Solar System after Proteus, a moon of Neptune.Its surface is dominated by a vast crater, with a diameter of 120 km and a depth of 10 km.The moon is then covered by a layer of dark material whose origin is still uncertain. It has been supposed that it can be methane from the atmosphere of Titan or material from Phoebe that has darkened its surface, similar to what happened on…
