Mesbin system document

Sun: F7V white star.

Shol: Superjool in a tight orbit around the Sun
-Yeerbor: retrograde planemo ball of salt and sand that travels between Shol's atmosphere and the edge of Shol's hill sphere.

Tiros: Desert planet with lakes at the poles.

Mesbin: Airless iron superkerbin, 3.2 gee at the poles, 0.8 gee at the equator. Rotates rapidly. Homeworld.
-Gramun: Airless rocky world, 0.672 gee.
-Kermun: Lush, habitable, 1.334 gee, 2 atm.
Derbin: 2.3 gee, 2.1 atm rocky superkerbin, distant binary orbit with Mesbin.
-Dermun: Mun-sized moon.
-Derminmus: dark brown, cratered version of Minmus.

Reander: 0.8 gee, green icy planet with a thick, oxygenated atmosphere. 15 atm of oxygen.
-Yalthe: small, yellowish world with lava-filled caldera and a thin volcanic-based atmosphere
-Cayn: A world where all of the air has fallen into thick canyons in the surface.
-Lito: A very large moon with very low gravity. 0.35 gee on a world twice the size of Kerbin.
-Yawer: Rapidly rotating moon of triaxial ellipsoidal shape. The ends of the moon are rotating greater than orbital velocity.

The Boulders: Degenerate Cores wrapped around a couple terrestrial planets, finally an excuse to make an ubertiny world. There are two of them, one an ocean world and the other an airless world.

Hypervelocity Rock: A comet in a hyperbolic orbit, travelling at roughly 300 km/s.
