Wolf 424 is a binary star system comprising two red dwarf stars. The stars are located at a distance of 14.37 light-years and hence are among the nearest stars, but due to their faint intrinsic brightness, they are not visible to the naked eye. Wolf 424 is located in the constellation Virgo, between the stars ε Virginis and ο Virginis.
