The Latest Breaking News from Solar System

The space agency has learned a lot over 10 years observing the weather of our solar system's outer planets.

Massive object passing through solar system is a better explanation for nature of orbits of Jupiter, Saturn and Neptune

Scientists are using chemical modeling to dissect whether life exists on icy moons in our solar system.

A pair of planetary scientists simulated how our solar system might have evolved if it had a super-Earth orbiting where the asteroid belt is today. The results are enough to make you grateful that we only have eight planets.

At this very moment, our solar system is hurtling through space at 450,000 miles per hour—a fact that is equal parts fascinating and terrifying. Yet, even as the solar system flies at a rate our tiny monkey brains can hardly comprehend, here on Earth we don't feel a damn thing.

The mini-moon 2024 PT5, which has been orbiting Earth for two months and is likely a chunk of the moon, will now drift away from our planet in an orbit around the sun.

Pluto and other large bodies in the Kuiper Belt are surprisingly rich in rock rather than ice. It may be because the early solar system consisted of much more carbon than previously thought, a new study suggests.

Samples collected from the near-Earth asteroid Ryugu have revealed clues about a primordial magnetic field that helped asteroids, planets and moons grow in our solar system.

Today, we know of more than 5,000 exoplanets: planets outside our solar system that orbit other stars. While the effort to discover new worlds goes on, we’re steadily learning more about the exoplanets we’ve already detected: their sizes, what they’re made of and whether they have atmospheres.
