O penAI's large language model (LLM) ChatGPT is surprisingly good at piloting spacecraft, according to a team that trained it ...

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new ...

A new paper examining and simulating the formation of wide-orbit planets has put the chances of our own Solar System harboring the hypothetical "Planet Nine" at up to 40 percent. In 2016, two ...

This link, called "trapping efficiency," shows how often scattered planets end up in stable wide orbits. The research found that in solar system-like conditions, trapping happens about 5–10% of ...

OF201, the object belongs to the same all-star family as Pluto: dwarf planets. Its diameter, roughly 435 miles (700 km), is half Pluto’s, ...

“This is David’s simulation ... some of these icy bodies come into the inner solar system, and we can see the orbit that they’re on,” Faherty said. “And they’re on these really crazy, long orbits. It ...

Astronomer breaks down "strongest evidence yet" of life on distant planet Astronomers announced Wednesday they have discovered a massive planet orbiting a tiny star, a bizarre pairing that has ...

Simulation: New telescope soon to detect millions of objects in the solar system In a few days, the first images from the Vera C. Rubin Observatory are to be presented.

Approximately 1,500–2,000 Centaurs, bodies on short-lived giant planet-crossing orbits in the middle solar system.

Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this year.

They then injected stellar flybys into the mix, adjusted for various distances that would result in different perturbation levels for planetary orbits. As Kaib noted, each simulation had slightly ...
