## Orbiting Kostne

B1-Kyto- is a scorched D-class. It orbits very close in and has a period of 4.8 days. Its mass is 2.6 earths, its diameter is 1.1 earths, its gravity is 2 gees, and its atmospheric pressure is 13 atms. It has 5 moons, one of which is a hot D-class named Dremir. Dremir's day is 11 hours 44 minutes long, and Dremir is a tenth of Kyto's diameter and 0.0034 Earth masses. It has .17 earth gravities and a very thin atmosphere.

B2-Etre- is a hot N-class. It orbits at .008 AU with a period of 10.6 days. Its mass is 13 earths, its diameter is 3.4 earths, and its gravity is 1.1 gees. It has 6 moons- asteroids ranging from 144-51 km in diameter. Notably, its aurorae are purple.

## Orbiting Both

1-Nezlir- is a frozen T-class world, orbiting at 237 AU and taking 3124 years to orbit, and has a day of 19 hours 40 minutes. It has one remarkable feature- Ice caps! They are frozen OF_{2}, and the only reason they don't cover the whole world (it's 20 degrees below OF_{2}'s freezing point at the poles) is areas of mild geothermal activity across the equator that keep it those 20 degrees above. As a result, the continents are water ice, silicates, and HF; while the oceans are liquid OF_{2}. Nezlir has a mass of .91 earths, a diameter of 1.2 earths, gravity of .67 gees, and a thin atmosphere. Nezlir has one moon- a frozen I-class with a gravity of .25 gees, a diameter of .6 earths, a mass of .09 earths, and a very thin atmosphere.

2-Dusyel- is a frozen I-class planet, orbiting at a whopping 509 AU with 9845 years to orbit. Its day is 14 hours 15 minutes. Its mass is 4.7 earths, its diameter is 1.9 earths, its gravity is 1.1 gees, and it has a very thin atmosphere.
