- How Do Planets Form? - Science@NASA
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
