Binary stars A star system with 2 stars orbiting it Globular cluster Its a collection of stars (it can be thousands to millions!) that is held together by gravity White dwarf A faint dying star a low or meteor mass collapsed to a small size it used to be a red giant. Neutron star A neutron star is a star that is made completely out of neutron it is very hot. Red giant A red giant is a luminous giant star it is yellow orange to red in colour. Nebulae A nebulae is a cloud of dust hydrogen gas helium and plasma Supernova A supernova is a stellar explosion that is more energetic than a nova Black hole A black hole is a giant hole that sucks things in nobody knows what is inside a black hole because if you go in one you cant get out.
