Is this our next place we can call Earth 2.0 .Proxima Centauri is a red dwarf, a small low-mass star, about 4.25 light-years from the Sun in the constellation of Centaurus. It was discovered in 1915 by the Scottish astronomer Robert Innes, the Director of the Union Observatory in South Africa, and is the nearest known star to the Sun. With an apparent magnitude of 11.05, it is too faint to be seen with the naked eye. Proxima Centauri may form a third component of the Alpha Centauri binary star system, but at a separation of 15,000 ± 700[18] AU its orbital period is likely greater than 500,000 years.
