Yes, it is. It is the third closest star to The Sun (Sol) after Proxima Cenaturi and Barnard's Star. "A very cool, main sequence red dwarf (M5.8Ve), Wolf 359 is our Sun's dimmest stellar neighbor within 10 ly, with less than 2/100,000th of Sol's luminosity." It is 7.8 light years aways and is in the constellation Leo.

Wolf 359 is a star located approximately 2.4 parsecs or 7.80 light years from Earth's solar system. It is one of the nearest stars to the Sun; only the Alpha Centauri system and Barnard's star are known to be closer. Its celestial position is in the constellation Leo, near the ecliptic. It is an extremely faint red dwarf, too dim to be visible to the naked eye, and it is a flare star.
The star was discovered using astrophotography by German astronomer Max Wolf in 1918. Its closest neighbor is Ross 128, 1.16 pc or 3.79 ly away.
