Barnard's Star


Barnard's Star is a dim, low-mass red dwarf located about 6 light years from Sol.  Barnard's Star is the fourth closest star to Sol.  Barnard's Star has roughly 17% of Sol's mass, 15% of it diameter, and is considered metal poor with only 30% its metallicity.  With an ago of over 10 billions years, Barnard's Star is considered a very old star.


Peter van de Kamp once believed that Barnard's Star had at least one Jupiter sized planet in its system, but was later found to be an error and incorrect.  Because of its how close Barnard's Star is to earth, it has always been a heavily studied.


Barnard's Star is approaching Sol at a fast speed of 140 km per second, it's believed that Barnard's Star will get as close as 3.8 light years in around 10,000 years.


The Barnard's Star system contains 3 planets.  One of the planets in the Barnard's Star system is home to an abandoned science station.  The planet has a thin atmosphere and orbits close to Barnard's Star.  Even at this close distance the planet is still very cold because of the dimness of Barnard's Star.  The scientific research station is  occasionally inhabited by vagrants and criminals for short periods of time.


Barnard's Star was one of the first system's explored after the restoration of interstellar travel.  The lack of easily habitable planets around Barnard's Star meant the first explorers spent only a small amount of time in the Barnard's Star system.  They visited and mapped the Barnard's Star planets then moved on to more fruitful systems.

Barnard's Star Planets
Barnard's Star B

Barnard's Star B
The closest planet to Barnard's Star is Barnard's Star B.  The planet is a hot world under a carbon dioxide atmosphere, heated to high to temperatures due to its closeness to Barnard's Star.

Distance: 0.027 AU

Orbit: 4 Days

Radius: 4122 km

Gravity: 0.48 g

Rotation: -

Barnard's Star C

Barnard's Star C
Sitting about 0.3 au from Barnard's Star is the planet Barnard's Star B.  Barnard's Star C is home to an abandoned science station which  once studied red dwarf stars.  Despite its close distance to Barnard's Star the planet is still very cold because of the the dimness of Barnard's Star.
