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 ...

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.

Neptune's elliptical, oval-shaped orbit keeps the planet an average distance from the sun of almost 2.8 billion miles (4.5 billion kilometers), or roughly 30 times as far away as Earth, making it ...

Researchers have shared a radical new idea for how to put a spacecraft in orbit around Neptune: Use the thin atmosphere of Triton, Neptune's largest moon, to capture it. The only spacecraft to ...

The bright S/2002 N5 moon is 14 miles (23 kilometers) in diameter and takes nearly nine years to complete an orbit of Neptune, while faint S/2021 N1 is about 8.7 miles (14 kilometers) across and ...

Chinese scientists propose 2033 Neptune orbiter mission Scientists are proposing China’s first ice giant mission, aiming to ...

This oblong orbit hints at complex gravitational interactions, both with Neptune and with the pull of the Milky Way's gravity. "There may have been more than one step in its migration," study co ...

With Pluto spending 20 years of its 248-year orbit within the orbit of Neptune, you might expect that at some point, the two worlds could catastrophically collide. However, Pluto and Neptune never ...

It is 14 miles wide and appears to be in a 9-year orbit around Neptune. The fainter moon is named S/2021 N1 and it is about 8.6 miles wide. It circles the planet once every 27 years.

Earth has a newly-discovered neighbor in the solar system.. But the heavenly body – possibly a dwarf planet à la Pluto – isn't a frequent visitor. Located beyond Neptune, its extreme orbit ...

Earth lives in a shooting gallery, with small and large rocky bodies in abundance in our solar system. Are we in danger of ...
