How it is formed Protoplanetary disks are formed by surrounding components of close binary systems with respect to temperature and size (“Binary System (astronomy)”). Binary System – a star system consisting of two stars orbiting around their common center of mass. It consists of brown dwarfs, planets, galaxies and asteroids
