Explanation

A white dwarf is a stellar remnant composed mainly of electron-degenerate matter - essentially the exposed core of a star that has exhausted its nuclear fuel. They are very dense but small in size (about Earth-sized) and slowly cool over billions of years. Constellations are star patterns, comets are icy bodies, and asteroids are rocky objects.
