Protoplanetary Disk

A protoplanetary disk is a rotating circumstellar disk of dense gas surrounding a young newly formed star (“Protoplanetary Disk”)

Circumstellar Disk- revolving around or surrounding a star.

This shows a newly formed star surrounded by a swirling protoplanetary disk of dust and gas (Formation of Planets in Protoplanetary Disk).

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

This protoplanetary disk is the seed material from which planets then form
