Astronomers have recently detected a colossal object at the edge of our solar system, sparking excitement and curiosity ...

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

'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 ...

According to a new study, a low-mass supernova roughly 12 times heavier than our sun may have triggered a gravitational collapse that eventually created our solar system.

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

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.

A new view of the solar system's early days proposes that the first two kinds of solid materials — the precursors of space rocks and ultimately planets — both formed at the same time.

Since the first discovery of planets beyond the solar system in 1995, more than 6,000 exoplanets have been identified. Many ...

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 ...
