Which is the star nearest to our solar system?

Answer 1

Proxima Centauri, a red dwarf of apparent magnitude #11.05# at a distance of about #4.24# light years from our sun is the nearest known star to our sun.

Proxima Centauri may have an orbital period longer than 500000 years, but it is most likely a member of a triple star system alongside Alpha Centauri A and B.
