The closest star to the sun is called Proxima Centauri. It is a red dwarf star located in the Alpha Centauri star system, which is about 4.24 light-years away from our solar system. Proxima Centauri is about 1/7th the size of our sun, and much cooler, with a surface temperature of about 3,000 Kelvin.

Proxima Centauri was discovered in 1915 by the Scottish astronomer Robert Innes. It was not until the 1960s that astronomers were able to determine its proximity to our solar system, thanks to advances in telescope technology.

While Proxima Centauri is the closest star to our sun, it is not visible to the naked eye from Earth. It is part of a triple star system that includes two brighter stars, Alpha Centauri A and B. Alpha Centauri A and B orbit each other closely, while Proxima Centauri orbits the pair at a much greater distance.
