Not long after Neptune completed its first orbit around the sun since its discovery in 1846, scientists have managed to calculate the exact length of one day on the distant gas giant planet.
According to Rufu, a collision with a large enough satellite in a prograde orbit, along the same path as the planet's rotation, would have thrown Triton into Neptune.
Explore all 16 of Neptune's moons along with their names and dates of discovery. The Neptunian system hosts some very strange and elusive moons.

A passing star, or a stellar flyby, with the potential to pull Neptune out of its orbit by just 0.1%, could mean catastrophe for the entire solar system. But don’t worry — it won’t happen in ...
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 is how long a year is on other planets in our solar system, beginning with Mercury at about 176 Earth days to complete its orbit.
The planet’s orbit is made even stranger by the fact that it is “backwards”: TIC 241249530 travels in the opposite direction to its star’s rotation.
Uranus Uranus is tilted almost completely on its side, placing its rotation on nearly the same plane as the planet's orbit around the sun, which lasts a staggering 84 years.
