as the sun is a star,it is the first nearest star to earth.
Alpha Centauri, closest star system to Earth and third brightest star in the sky. Alpha Centauri is located in the constellation Centaurus and is sometimes called Rigil Kentaurus, which literally means “foot of the centaur.” Alpha Centauri is actually a triple star system that appears as a single point of light because its two largest and brightest members, Alpha Centauri A and Alpha Centauri B, are too close together for the naked eye to tell them apart and its third member, Alpha Centauri C, is too small and dim to be seen at all. The Alpha Centauri system is only visible from the Southern Hemisphere and the southernmost portion of the Northern Hemisphere. In Texas, Louisiana, and Florida, for example, it appears very low in the southern sky and is most easily visible in May.
Alpha Centauri A and Alpha Centauri B lie about 4.35 light-years from Earth.
Alpha Centauri A is a yellow star, slightly larger and brighter than the Sun, of spectral type G2 and apparent magnitude +0.01. Spectral type indicates a star’s surface temperature and the predominant color of the light it gives off. Apparent magnitude is a measure of how bright stars appear in the sky—a small, nearby star may appear just as bright as a much larger star that is farther away. The lower the apparent magnitude, the brighter the star appears. Alpha Centauri B is a yellow-orange star somewhat smaller and cooler than the Sun of spectral type K1 and apparent magnitude +1.34. Proxima Centauri is a red dwarf star of spectral type M5, much smaller and cooler than the Sun.
