Two of Neptune's innermost moons perform a strange dance to avoid each other that is weird and completely unique compared to all known orbits, according to new research.

Neptune's orbit is shaped roughly like an oval, with the planet taking about 165 years to complete a single circuit. The average distance between Neptune and the sun is nearly 2.8 billion miles (4 ...

Neptune takes about 165 years to complete one orbit around the sun. It is about 30 times farther from the sun than Earth and typically orbits at a distance of about 2.8 billion miles (4.5 billion ...

Neptune is big, it’s blue, and it is a planet that can tear you apart if you happen to drop into one of its massive, ...

The study shows that even an 0.1 percent change to Neptune’s orbit could completely destabilize our solar system. Luckily, it won’t happen in our lifetime.

Although astronomers have only found four Trojan asteroids near Neptune, they suspect that there may be hundreds more clustered in its orbit. Credit: Science ...

Today, Neptune has arrived at the same location in space where it was discovered nearly 165 years ago. To commemorate the event, NASA’s Hubble Space Telescope has taken these “anniversary […] ...

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 ...

Half a dozen planets - Mercury, Venus, Jupiter, Saturn, Uranus and Neptune - will put on a dazzling display in the sky on ...

Neptune takes about 165 years to complete one orbit around the sun. It is about 30 times farther from the sun than Earth and typically orbits at a distance of about 2.8 billion miles (4.5 billion ...

The small object sports a peculiar, tilted orbit that places it in orbital resonance with Neptune at a ratio of 10:1. This means the two celestial bodies affect each other’s motion, locking them ...

Three new objects locked into roughly the same orbit as Neptune--called "Trojan" asteroids--have been found by researchers from the Carnegie Institution's Department of Terrestrial Magnetism (DTM ...
