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 ...

Sedna will make its closest approach to the Sun in 2076, giving us a rare opportunity to visit the planetoid before it drifts ...

A recent study has uncovered a dramatic interaction between a planet and its parent star that is reshaping our understanding ...

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 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.

If a star flying past our solar system moved Neptune's orbit by just 0.1 per cent, it could eventually cause the other planets to smash into one another or get thrown out of the solar system entirely.

Artist's impression of Planet Nine – a suspected “wide-orbit” planet – with the Sun in the distance; Neptune's orbit is shown ...

A star getting too close to our solar system could cause chaos (Picture: PA) Researchers have found that if a star flying past our solar system moved Neptune’s orbit by just 0.1 per cent, it ...

The gas giant planet Neptune takes center stage in a series of sharp new photos snapped by the Hubble Space Telescope in honor of the blue-green world's first Neptunian year around the sun since ...

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 ...
