Explore solar system dynamics, revealing the chaotic formation of planets and the unique paths that shaped our cosmic neighborhood.

Our solar system's latest and only third known interstellar visitor is becoming more fascinating by the minute. Spotted in early July, the object, dubbed 3I/ATLAS, is believed to be a comet. It's ...

This breakthrough could change how we understand the Solar System's formation and history, and it suggests similarities between our Solar System and other planetary systems, which holds important ...

'Little Bang' Triggered Solar System Formation Date: October 3, 2008 Source: Carnegie Institution Summary: For several decades, scientists have debated whether the Solar System formed as a result ...

A new theory of the solar system's formation provides an alternative to the idea our system formed from a supernova.

Learn how rock and dust samples are shedding light on the origins of Asteroid Bennu and the history of the early Solar System ...

Called 3I/ATLAS, the object is only the third of its kind known to astronomers, and it’s likely been heading our way for billions of years, carrying pristine material from another star system ...

Why are the planets of the inner Solar System dry and rocky, but the outer ones are not? Researchers discovered that a two-step formation process of the planets can explain the chronology and split in ...

The solar system features a unique dichotomy of planets -- the inner solar system features smaller, drier bodies, while the planets found in the outer solar system are larger and wetter.

The early solar system was a violent place: it wasn't just asteroids, but whole planets that veered on strange courses. (Photo credit: NASA) When most of us learn about the solar system, it seems like ...

In comparison, outer Solar System planetesimals formed later and therefore experienced substantially less internal heating and therefore limited iron core formation, and volatile release.

When most of us learn about the solar system, it seems like a pretty well-ordered place. Our Sun formed first, about five billion years ago, and the planets appeared a little later. As a very ...
