Protoplanetary disk - Simple English Wikipedia, the free encyclopedia

A protoplanetary disk is a rotating circumstellar disc of dense gas and dust surrounding a young star that has just formed. Protoplanetary disks have radii up to 1000 AU. Protoplanetary disks have been seen around several young stars in our galaxy.^[1]

Protoplanetary disks are thought to be thin structures. They have mass that is much smaller than the young star in the center.^[2]
