Wolf 359

Wolf 359 is a red dwarf that is located in the constellation Leo, near the ecliptic. At a distance of approximately 7.8 light years from the Earth, it has an apparent magnitude of 13.5 and can only be seen with a large telescope. Wolf 359 is one of the nearest stars to the Solar System; only the Alpha Centauri system (including Proxima Centauri), Barnard’s Star, Luhman 16, and WISE 0855–0714 are known to be closer.

Wolf 359 is one of the faintest and lowest-mass stars known. At the light-emitting layer called the photosphere, it has a temperature of about 2,800 K, which is low enough for chemical compounds to form and survive. The absorption lines of compounds such as water and titanium(II) oxide have been observed in the spectrum. The surface has a magnetic field that is stronger than the average magnetic field on the Sun. As a result of magnetic activity caused by convection, Wolf 359 is a flare star that can undergo sudden increases in luminosity for several minutes. These flares emit strong bursts of X-ray and gamma ray radiation that have been observed by space telescopes. Wolf 359 is a relatively young star with an age of less than a billion years. No companions or disks of debris have been detected in orbit around it.

Due to the lack of planets or even asteroids and the bursts of gamma and x-rays few people visit this system intentionally.
