Formation and evolution of the Solar System apart by tidal interactions. Afterwards, all that will remain of the Sun is a white dwarf, an extraordinarily dense object, 54% its original mass but only the size of the Earth. Initially, this white dwarf may be 100 times as luminous as the Sun is now. It will consist entirely of degenerate carbon and oxygen, but will never reach temperatures hot enough to fuse these elements. Thus the white dwarf Sun will gradually cool, growing dimmer and dimmer. As the Sun dies, its gravitational pull on the orbiting bodies such as planets, comets and asteroids will weaken due to its
East of the Sun (and West of the Moon) East of the Sun (and West of the Moon) "East of the Sun (and West of the Moon)" is a popular song written by Brooks Bowman, an undergraduate member of Princeton University's Class of 1936, for the 1934 production of the Princeton Triangle Club's production of Stags at Bay. It was published in 1934 and soon became a hallmark of the Princeton Tigertones, one of Princeton University's all-male a cappella groups.
