Wolf 359 lies in the northern constellation Leo. Discovered by Max Wolf in 1918, it is an extremely faint red dwarf that for 25 years was the least luminous star known. It is also a flare star with the variable star designation CN Leonis, and in 2001 became the first star, other than the Sun, to have its corona registered by near-optical ground-based detection when an emission line of highly ionized iron (Fe XIII at 3,388 Å) was reported. In 1997, the Hubble Space Telescope (HST) in combination with the Faint Object Spectrograph (FOS) was used to search for faint companions – faint stellar or large sub-stellar objects, such as brown dwarfs – around Wolf 359. The images obtained (see above) show no such orbiting body as close as 1 astronomical unit (AU), equivalent to an angular separation of 0.432 arcseconds, from the star. visual magnitude 13.45 absolute magnitude 16.56 spectral type M6Ve luminosity 0.00002 Lsun distance 7.78 light-years (2.386 pc) position RA 10h 56m 29.2s, Dec. +07° 00' 53" other designations CN Leonis, GCTP 2553, GJ 406, G 045-020, LTT 12923, LFT 750, LHS 36 Science fiction connections In the Star Trek universe, Wolf 359 was the scene of a battle in 2367 between the Federation and the Borg. This was depicted in the Next Generation episode "The Best of Both Worlds". "Wolf 359" is the title of an episode of the original series of The Outer Limits in which a scientist creates a miniature version of a planet going around the star in his own laboratory on Earth.
