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 general ...

In a new study published in the Astrophysical Journal, astrophysicists Brooke Polak from the University of Heidelberg and Hubert Klahr from the Max Planck Institute for Astronomy used simulations to ...

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

Astronomers gazed at a distant protostar, and what they saw revealed that the water in our solar system likely formed long before our Sun was born! Astronomers appear to have found the missing link ...

A tiny comet fragment from the outer edges of the solar system was found on Earth — inside a meteorite. Scientists discovered a tiny blob of carbon about the width of a human hair inside a rocky ...

Super-Earths and sub-Neptunes, planets with sizes between Earth and Neptune, constitute approximately one-third of known exoplanets but are absent in our solar system. Their prevalence elsewhere and ...

An interstellar visitor may have warped the solar system billions of years ago, a new study has claimed. Scientists suggested the enormous object disrupted the orbits of Jupiter, Saturn, Uranus and ...

The planets in solar do not have circular orbit around the Sun, including Earth which goes around in an elliptical orbit. A ...
