Barnard's Star is a red dwarf 6 light-years
from Sol, famous for having the highest proper
motion (movement across the sky from earth's point of view) of any star. There are
four planets occupying a narrow band of orbits near the primary.
A small world, rather like Mars. It orbits at 8% of Earth's
distance from the sun, has a strong inclination from the ecliptic, and
is tidally locked. Due to the thin atmosphere and proximity to
the star, this planet is constantly bathed in strong radiation and the
day side is uninhabitable.
A rocky and cold world, somewhat smaller than Earth. It has a
thin atmosphere, resulting in slower erosion of the surface. A
mysterious spacecraft of unknown origin was discovered here.
A roughly earth-sized world. It was an important source of
metals and other resources for Alpha Centauri during the Proximan War,
but it was attacked in one of the enemy's last major actions and
the surface was heavily contaminated by radiation. There are two
orbital bands of captive heavy metal satellites.
An icy planet.
