A protostar was a celestial object.
Behind the scenes
While the 2017 reference title Star Wars Made Easy states that the celestial object that the Alliance Fleet gathered before was a protostar, the 2020 reference title The Star Wars Book states that the fleet was gathered at the edge of the galaxy, in view of the latter celestial object that was previously established to be a protostar.
