Washington, DC – 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 ...

Neptune’s moon Nereid may be the sole survivor of an ancient moonpocalypse. A new study suggests that the strange satellite was born in a steady, circular orbit around Neptune, then tossed into its ...

Far beyond the bright planets, in the dim outskirts of the Solar System, astronomers keep stumbling on objects that refuse to follow the rules. Around Neptune in particular, a handful of newly charted ...

Imagine a world the size of Neptune, but instead of following the orderly path of its neighbors, it is racing headlong against the flow of its own solar system. In the case of the exoplanet TOI-1710 b ...

A Neptune-sized planet, TOI-3261 b, makes a scorchingly close orbit around its host star. Only the fourth object of its kind ever found, the planet could reveal clues as to how planets such as these ...

The farthest planet from the Sun has a rather strange collection of moons in its orbit. That may be because Neptune’s largest moon, Triton, made a mess when it forced its way into the planet’s orbit ...

Why there are few Neptune-sized exoplanets orbiting very close to other stars Why not all exoplanets orbit their stars in an orderly fashion How astronomers can work out the 3D shapes of the orbits of ...

Our solar system has a few new entries with the recent discovery of three moons of Uranus and Neptune. These ice giant planets are so far away that it is difficult to detect small moons orbiting them, ...

Neptune is the solar system's most distant planet, a cold, blue ice giant sitting nearly 30 times further from the sun than Earth. At that remote distance, temperatures plunge to nearly minus 200 ...
