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

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 ...

No one knows, but other available information shows that the formation of Earth and the Moon was one of the latest events in the genesis of the Solar System, and occurred 4.543 billion years ago.

Our Solar System formed from a gas cloud about halfway towards the edge of the disk, about 25,000 light-years from the center, in the central part of the disk if you were to slice it length-wise.

Our solar system is estimated to be about 4.57 billion years old. Previous analyses of ancient meteorites have shown that minerals were created through chemical reactions with water as far back as ...

“The gas giants must have formed by 4 million years after the formation of the solar system,” Weiss says.

Scientists have found how our solar system was formed in the wind-blown bubbles around a giant, long-dead star.

According to one longstanding theory, our Solar System's formation was triggered by a shock wave from an exploding supernova. It injected material from the exploding star into a neighboring ...

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 solar system lost its ninth planet back when Pluto was demoted to a dwarf planet, but research might indicate that there ...
