Join a Planetary Science Project

Amateur astronomers and volunteer (citizen) scientists discovered most of the known planets and comets, and they continue to make major contributions to planetary science research. Anyone around the world can join NASA’s planetary science efforts as an amateur/citizen scientist by participating in one of the projects below.
