  Barnard's Star
Barnard's Star, an old and very dim red dwarf, was once thought to have two Jupiter-class planets.
The star was named after its discoverer, noted astronomer Edward Emerson Barnard (1857-1923), who found in 1916 that the star has the largest known proper motion of all known stars (10.3 arcseconds per year).
Its high space motion and sub-Solar metallicity suggests that the star is "intermediate Population II star," somewhere between a Halo and a disk star (Kürster et al, 2003; and John E.

Because of the vast distances between us and stars, the stars appear to be glued in the night sky and that the only apparent movement of stars that we see is due to the rotation of the Earth about its axis.
Because Barnard's Star is a red dwarf (common in our galaxy), its close proximity to us, and its large proper motion, this star was a prime candidate for further study regarding the search for extrasolar planets.
According to van de Kamp, a wobble in the movement of Barnard's Star was detected which he determined was the result of a body revolving around the star.

 Main
This very modest little star, located just six light-years away in the direction of the constellation Ophiuchus, is the closest star that can be studied from the Northern Hemisphere -- but only with the aid of telescopes, since it is much too dim to be seen with the unaided eye.
But stars that are quite nearby can change their positions relatively rapidly, just as an automobile on a street right next to you zips past you quickly, but cars on a distant highway seem to crawl along.
Barnard's Star moves across the sky at a rate of about half a degree (the size of the Moon's diameter) every 175 years.

The star is a white star about 130 time as luminous as the Sun and it does have a magnitude 7.7 companion star which is itself again a close double star.
It is a beautiful binary star with the primary component being orange and the secondary star being of yellowish appearance.
Its spectral type indicates that Barnard's Star is cool: Only about 3200 K. Van de Kamp had announced the discovery of the presence of at least one planet of 1.5 times the mass of Jupiter at a separation of 2.4 arc seconds, or 4 Astronomical Units.

 HubbleSite - NewsCenter - Ghostly Reflections in the Pleiades (12/06/2000) - Introduction
Astronomers have proposed that the strong starlight shining on the dust in the cloud decelerates the dust particles.
Thus, as the cloud approaches the star, there is a sifting of particles by size, much like grain thrown in the air to separate wheat from chaff.
The nearly straight lines pointing toward Merope are thus streams of larger particles, continuing on toward the star while the smaller decelerated particles are left behind at the lower left of the picture.

 Mission to Barnards Star - Bad Astronomy and Universe Today Forum
At the time people thought Barnard's star had a planet or two, but later study shows that those measurements were spurious.
Barnard's Star is a halo star, which means it spends most of its time way above or below the galactic plane.
Being a halo star also means that it is ancient--perhaps 11-12 billion years old--and is devoid of heavier elements.

 BARNARDS STAR
Barnards Star II was a very cold world (–168C) and has a methane weather system, methane and other hydrocarbons rain down on the planets icey surface in a situation similar to that of Saturn’s largest moon, Titan.
Barnard’s Star did not start with a system government or written constitution, in fact the system became a hive of lassiez-faire capitalism (except for the scientific outposts on Klein) as industry prospered in the orbitals and asteroid colonies.
When a wormhole from Sol was constructed in 2570 the system got a great boost in tourism from those wishing to study the haunting and alien beauty of Klein’s World to those wishing to blow their money in gaudy casino’s and nightclubs in orbit around van de Kamp.

Also cataloged as Munich 15040 or LFT 1385, Barnard's Star was discovered in 1916 by E.E. Barnard to have the largest known proper motion of all stars, 10.29 arc seconds per year, by comparing photographic plates obtained in 1894 and 1916, and later tracing it back to 1888 in E. Pickering's plate archive.
According to Burnham, the star will reach a minimum distance of less then 4 light years in about 8,000 years, when its proper motion will have reached 25 arc seconds per year and its brightness will be about magnitude 8.6.

The further away a star is the smaller the wobble is and the wobble is lost in the noise of the measurements.
Barnards star was the next candidate for this technique as it has the largest proper motion of any star (10.3 arcseconds per year [34]) and it is relatively close to the Earth (6 light years).

Quadrants are generally named after the most politically significant star present, or else the most significant astrographic feature in areas with very low populations.
Distant quadrants are usually noted as “Far Stars”, along with a north/south notation and an east/west notation.

I'm thinking it would be cool to design a computer program that would automatically assign names to newly discovered stars that have only codes.
Something to consider is that 98% of heavenly objects are only of interest to scientists(astronomers), so there's no point in coming up with a bijillion names for everything.
This particular one is of course of scientific interest, but it's probably too small to support life, original or colonized, so generally it's of no practical use for humanity (if we get out of the system).
