Is our Sun a binary star?


The Sun is a star. Specifically, it is a type of star called a yellow dwarf. The Sun lies in the Milky Way galaxy, and it is the center of the Earth's solar system. It provides the energy necessary to sustain life on Earth.

Answer and Explanation:

No, the Sun is not part of a binary star system. It is the only star in the Earth's solar system. The closest binary system to Earth is Sirius. It is about 8.6 light years from Earth. It consists of a white dwarf and a large, blue star.

Eventually, the sun will expand into a red giant and then collapse into a white dwarf.
