Border system

The Border System is so named because it lies exactly on the border of the Expansion Region. Its star, Pin is yellow-white and medium in size. Pin is surrounded by six planets, one of which, Holt, is habitable. Of the other, four are gas giants and the other is too small to contain an atmosphere. There are also four charted dwarf planets, and 213 charted moons, most of them orbiting the gas giants.
