The Sun ofcourse, but if you mean other than the Sun, then it is Proxima centuri.
The red dwarf star Proxima Centauri, part of the Alpha Centauri star system, is the nearest star to the Sun. As the name suggests, it is located in the constellation of Centaurus. Proxima Centauri was discovered to share the same proper motion as Alpha Centauri in 1915 by Robert Innes while he was Director of the Union Observatory in Johannesburg, South Africa. It was Innes who suggested the name Proxima. In 1917 at the Royal Observatory, Cape of Good Hope, J. Voûte measured the trigonometric parallax and determined that Proxima was indeed at the same distance as Alpha Centauri, and hence was also the faintest star known at the time.
Alpha Centauri (α Cen / α Centauri) is the brightest star in the southern constellation of Centaurus. Although it appears as a single point to the naked eye, Alpha Centauri is actually a system of three stars, one of which is the fourth brightest star in the night sky. Alpha Centauri is famous in the Southern Hemisphere as the outermost “pointer” to the Southern Cross, but it is too far south to be visible in most of the northern hemisphere. The two brightest components of the system are too close to be resolved as separate stars by the naked eye and so are perceived as a single source of light with a total visual magnitude of about â0.27 (brighter than the third brightest star in the night sky, Arcturus).
Alpha Centauri is the closest star system beyond our own solar system, being 4.39 light-years distant (about 25.8 trillion miles or 277,600 AU) (Proxima Centauri, often regarded as part of the system, is 4.26 light-years distant). This makes it a logical choice as "first port of call" for speculative fiction about space travel, which often assumes eventual human exploration of the system or even colonization of possible planets within it. Such themes are found in said speculative works of fiction such as novels and video games.

By definition a Star is an object that emits more energy than it absorbs.
1. By that definition the Earth must be a star.
2. The Sun is obviously a star.
3. Jupiter emits more radio energy than it absorbs. In fact it is classed as a radio star.
