It is possible (very minute possibility) that a rogue white dwarf star could pass by the Sun and alter it's shape (egg, oval, weird) quite literally. If this white dwarf star were to penetrate the Sun, it would explode in a Nova. The sun, by the way, is plasma, so it'd just initially absorb it (plasma closest to liquid state). Then -pop- No more.
