Circumstellar disks are made up of dusts and gas orbiting a star. Younger, gas-filled protoplanetary disks are the birthplaces of planets, and older debris disks that have lost their gas can stay around a long time after the planet has formed. There is still a debris disk in the Milky Way Solar System called the Kulper Belt. This project gives citizen scientists the opportunity to classify disk debris and help scientists to better understand how planets form and predict where planets might be based on the shape of the debris disk.
