White dwarf
Red dwarves are failed stars that never attained the mass necessary to become a full-on star. Jupiter actually isn’t far off from this status.
On a related note, red dwarves will probably be some of the last sources of light in the universe, and live for trillions of years due to how slowly they burn fuel, so.. suck it, Shapiro?
Jupiter's quite a long way off from being a red dwarf it would need to be in any 10 times the mass be a red dwarf.
Jupiter is somewhat close to being a brown dwarf which is a star that failed to even become a failed star and is merely hot and glowy but not plasma. Jupiter's atmosphere is just gaseous though perhaps really deep down at the core it achieves brown dwarf level status but we don't consider it to count because it's not the whole planet.
Red dwarfs are not failed stars. They are the lowest mass objects capable of nuclear fusion. Brown dwarfs are failed stars. Brown dwarfs officially start at 13 Jupiter masses, & have a maximum mass of 75 Jupiter's. Beyond that mass, fusion starts & the object is officially a star.
