If the name seems familiar then its probably you`ve heard it in Star Trek - The Next Generation as it was the scene of a battle between the Federation and a Borg Cube which didn`t end well for the Federation. It was featured in the episode The Best of Both Worlds and saw Captain Jean-Luc Picard be assimilated into the Borg. It was also the site where Captain Benjamin Sisko lost his wife during the battle.
It is one of the closest stars to our Sun at a mere distance of 7.82 light years. There are closer stars to our Sun which include Proxima Centauri, a mere four and a bit light years from here. Even though it is close by, you won`t be able to see it because it is faint. The fact that its close by is one of the reasons why its popular in fiction.
The location of the star in the galaxy is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is from celestial equator. The Declination is how up or down compared to the celestial equator and is expressed in degrees. For Wolf 359, the location is 10h 56m 28.99 and 7d 00' 52.0 .
Wolf 359 has a spectral type of M6.5 Ve. This means the star is a red coloured main sequence dwarf star.
Wolf 359 has been calculated as 0.16 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 111,328.00.km.
Wolf 359 has an apparent magnitude of 13.54 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
The star is a eruptive Eruptive s of the UV Ceti variable type which means that its size changes over time. The Variable Type is usually named after the first star of that type to be spotted.
The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Stellar Age, Metallicity or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
