Geomorteus
Class B or Geomorteus planets are the final resting place for Class A, geothermal planets, only one thousand to ten thousand kilometers in diameter. These planets are barren, most landforms being the result of impacts. These planets are between 90 million to ten billion years old. Geomorteus planets are usually completely solidified, but the younger members of this class may be partially molten, and may poses minor geological activity. Class B planets tend to have extremely tenuous atmospheres composed mainly of sodium and helium gas, because of this lack of an insulating atmosphere, the planet’s surface temperatures can range from 500 Kelvin during the day to 140 Kelvin at night.

Like the class of planet that precedes them, class B plants can exist anywhere in a system, although most class b planets tend to be within a stars hot zone. The extreme surface conditions tend to make these planets incapable of supporting life. Class B planets evolve from class A planets, a big difference between class B and class C planets is that Class B planets cool much faster than Class C.
