Ross 154

Ross 154

(V1216 Sgr) is a star in the southern zodiac constellation of Sagittarius. It has an apparent visual magnitude of 10.44,making it much too faint to be seen with the naked eye.

The distance 9.69 light-years (2.97 parsecs) away from Earth.

It is the nearest star in the southern constellation Sagittarius, and the 8th closest star system to SOL.

 This star was first catalogued by Pre Astro Earth astronomer Frank Elmore Ross in 1925

 Ross 154 was found to be a UV Ceti-type flare star, with a mean time between major flares of about two days. Typically, the star will increase by 3–4 magnitudes during a flare. The strength of the star's surface magnetic field is an estimated 2.2 ± 0.1 kG.[17] Ross 154 is an X-ray source. The quiescent X-ray luminosity is about 9 × 1027 ergs s−1.[9] X-ray flare emission from this star has been observed with a particularly large flare emitting 2.3 × 1033 erg.



A stellar classification of M3.5V makes this a red dwarf star that is generating energy through the nuclear fusion of hydrogen at its core. It has an estimated 17% of SOL's mass and 24% of SOL's radius,but it is radiating only 0.38% of the luminosity of SOL. In contrast to SOL where convection only occurs in the outer layers, a red dwarf with a mass this low will be entirely convective. Based on the relatively high projected rotation, this is probably a young star with an estimated age of less than a billion years.

The abundance of elements heavier than helium is about half that in SOL.

 The System has no Planets and no dust cloud

It is a Union Star System declared since 2339. It received a Union Space Fort in 2344 and has been earmarked as a second Fleet building site. The reason for this is the observation that enemies like the Y'All and the Galactic Council during the 4th Intergalactic war completley ignored planet less systems. This started the trend of Union logistics planners to chose such systems for ship yards and munition factories. Ross 154 has 18 Gigamon Stations and 1 Gigamon Plus as well as a number of Deep Space Factories and a massive ship yard.

It is now the logistic home of the X Fleet and off limits to civilians.
