How Do Planets Form?
Scientists think planets, including the ones in our solar system, likely start off as grains of dust smaller than the width of a human hair. They emerge from the giant, donut-shaped disk of gas and dust that circles young stars. Gravity and other forces cause material within the disk to collide. If the collision is gentle enough, the material
Solar system: Everything you need to know!
The solar system formed about 4.6 billion years ago from a giant molecular cloud of gas and dust. Over time, gravitational forces led to the formation of the Sun and the various objects that make up the solar system. The solar system provides a unique window into the study of planetary science, astronomy, and the origins of our cosmic neighborhood.
