Starforce: Alpha Centauri, the first mass market science fiction wargame produced, [3] was designed by Redmond A. Simonsen, who also did all the graphical design and artwork. The game was a bestseller for SPI, appearing on SPI's monthly Top 10 list 14 times.
The Alpha Centauri star system is the closest star system to the Sun. List of nearest M-type stars. This is a list of M-type stars ...
For example, Sirius, the brightest star in the sky, is actually a double star, consisting of the naked-eye visible Sirius A and its dim white-dwarf companion Sirius B. The first exoplanet tentatively identified around the second brightest star in the triple star system Alpha Centauri is accordingly called Alpha Centauri Bb.
Alpha Centauri (α Centauri, α Cen, or Alpha Cen) is a triple star system in the southern constellation of Centaurus. It consists of three stars: Rigil Kentaurus (α Centauri A), Toliman (α Centauri B), and Proxima Centauri (α Centauri C). [14] Proxima Centauri is the closest star to the Sun at 4.2465 light-years (1.3020 pc).
Capella is the brightest star in the constellation of Auriga (upper left). α Aurigae (Latinised to Alpha Aurigae) is the star system's Bayer designation. It also has the Flamsteed designation 13 Aurigae. It is listed in several multiple star catalogues as ADS 3841, CCDM J05168+4559, and WDS J05167+4600.
A multiple star system consists of two or more stars that appear from Earth to be close to one another in the sky. [dubious – discuss] This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star [a] Physical multiple ...
Proxima Centauri is a member of the Alpha Centauri star system, being identified as component Alpha Centauri C, and is 2.18° to the southwest of the Alpha Centauri AB pair. It is currently 12,950 AU (0.2 ly ) from AB, which it orbits with a period of about 550,000 years.
Procyon is a binary star system with a bright primary component, Procyon A, having an apparent magnitude of 0.34, [3] and a faint companion, Procyon B, at magnitude 10.7. [4] The pair orbit each other with a period of 40.84 years along an elliptical orbit with an eccentricity of 0.4, [ 9 ] more eccentric than Mercury 's.
