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.

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.

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 ...

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 ...

In a bit of cosmic coincidence, New Horizons' passage through Neptune's orbit 2.75 billion miles from Earth came 25 years to the day after NASA's Voyager 2 spacecraft flew past the giant blue ...

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.

In a recent paper, the team looked at long-period objects that crossed the path of Neptune's orbit, finding that their ...

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 ...

Neptune, a cold, unexplored world farthest from the sun, is getting its time in the light after the James Webb Space Telescope captured new images of the planet for the first time in decades.
