SOLAR SYSTEM

Detailed explanation-1: -The Sun is the largest object by far in the solar system. Its diameter, or distance through its center, is about 865, 000 miles (1, 392, 000 kilometers). This is about 109 times bigger than Earth’s diameter.

Detailed explanation-2: -The Sun is a yellow dwarf star, which means it is a medium size star. It is believed to be over 4 billion years old. The Sun spins slowly on its axis as it revolves around the galaxy. The center, or core, of the Sun is very hot.

Detailed explanation-3: -The two sunlike stars that make up Alpha Centauri are Rigil Kentaurus and Toliman. Rigil Kentaurus, also known as Alpha Centauri A, is a yellowish star, slightly more massive than the sun and about 1.5 times brighter.

Detailed explanation-4: -After spending about 1 billion years as a red giant, our own sun will become a white dwarf, packing most of its initial mass into a sphere roughly the size of Earth. This fate awaits many other stars as well-all of them that are less than about eight times more massive than the sun, in fact.
