But for Neptune, discovered in 1846, a single orbit takes a bit less than 165 Earth years — and the planet has now completed exactly one of those Neptunian years since it was first spotted by ...

Discovered in 1846, Triton is the only known large moon in the Solar System with a retrograde orbit, traveling in the opposite direction to the planet’s rotation. This fact indicates that ...

For years, scientists have suspected that Triton wasn't part of Neptune's original collection of moons. The massive moon has a backward orbit, and makes up over 99 percent of all the mass orbiting ...

By plotting a circular orbit of the moon, Showalter saw that the tiny satellite fully orbits Neptune every 23 hours. The tiny moon is so small and hard to see that it even evaded NASA's Voyager 2 ...

Neptune’s large moon Triton may have abandoned an earlier partner to arrive in its unusual orbit around Neptune. Triton is unique among all the large moons in the solar system because it orbits ...
