There are a couple of ways that scientists can date planets, so which planets formed first in our solar system?

Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected. Previous research suggests ...

Ever since scientists started looking at meteorites with microscopes, they’ve been puzzled–and fascinated–by what’s inside. Most meteorites are made of tiny beads of glass that date back to the ...

Scientists at the Massachusetts Institute of Technology and other universities are analyzing tiny particles from a distant asteroid to learn more about how the outer solar system was formed and shaped ...

You're probably familiar with how the solar system looks today. There are eight officially recognized planets located more or less on the same plane, orbiting the sun. But have you ever given a ...

Researchers studying meteor showers have found that not all comets crumble the same way when they approach the Sun. In a new study, they ascribe the differences to the conditions in the protoplanetary ...

In an article published in the journal Icarus, researchers at São Paulo State University (UNESP) and collaborators report the findings of a study reconstituting the formation of the dwarf planet Ceres ...

Discovery of oxygen raises new questions about how solar system formed. In this undated photo, Rosetta finds oxygen on comet 67P. ESA/Rosetta/NavCam – CC BY-SA IGO 3.0 — -- The European Space ...

About 4. 6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity.

The Sun's formation caused temperature differences in the surrounding disk of gas and dust. Inner, hotter regions formed rocky planets from less volatile elements. Outer, colder regions allowed ...
