The Sun rotates roughly once every 25 days (in reality it rotates at slightly different periods at different latitudes, unlike a solid body like Earth). Its radius and mass are roughly 7.0x10⁸ m and 2.0x10³⁰ kg. Someday when the Sun runs out of fuel, it will collapse into a white dwarf star with about 1% of its current radius. If it ejects no mass in the process (not a realistic assumption), what will be its rotational period as a white dwarf?
