Prevailing theoretical models attempting to explain the formation of the solar system have assumed it to be average. Now a new study by Northwestern University astronomers -- the first to model ...

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

Instead of just speculating about what our solar system would be like if Jupiter was a star, we decided to test it out. If you haven’t heard of it, there’s a program called "Sandbox Universe ...

New solar system formation models indicate that Jupiter's foray robbed Mars of mass Date: June 6, 2011 Source: Southwest Research Institute Summary: Planetary scientists have long wondered why ...

The NSF–DOE Vera C. Rubin Observatory is set to revolutionize our knowledge of the solar system's "small bodies"—asteroids, comets and other minor planets.

Comet 67P has a curious shape that was likely the result of a collision of two smaller comets. This simulation shows how these types of collisions can form. In particular, it reveals that even ...

Jupiter, the largest planet in our solar system, has recently celebrated a new birthday, pinpointing its formation to approximately 4.5 billion years ago. This significant revelation comes from the ...

They hypothesize that our solar system formed inside a massive space bubble, which was produced by a star 40 to 50 times the size of our sun. The research was published today in Astrophysical Journal.

“The fact that a simulation of planet formation produces an end state in good agreement with the observed solar system does not prove that the simulated events actually happened,” he writes.

Prevailing solar system formation theories indicate that these planets should have at least started out following perfectly circular and share the same orbit.
