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
Partial/total eclipses on the Moon center of the Earth's shadow while the remainder visilbly as partial, some has 50/50 covered by the center of the Earth's shadow and visibly as partial. The shortest can be for around 2 hours and the longest can be up to 5–6 hours. Partial/total eclipses on the Moon Partial/total Solar eclipses on the Moon are caused when the Earth passes in front of the Sun, blocking a part its light in one part and the whole light in the other. Viewers on Earth will see a partial lunar eclipse. During its eclipses, the Earth will be in new phase, completely
