Formed by Gravity

A few billion years ago, our solar system was just a cloud of dust and gases loosely held together by gravity. In this visualization, you will watch how gravity pulled those gases and debris together to slowly form the sun and planets we see today. Watch events that took millions of years unfold before your eyes! You can also fast-forward or rewind by holding down the time marker and moving it forward or back. Which planet or planets were the last to take shape?
