13 Orionis


13 Orionis is a planetary system orbiting a yellow G-class star.  The system lies in the Orion Constellation of the Hyades Region.

13 Orionis is a multiple planet system orbiting a subgiant star, which is quickly growing into a giant.  The worlds have changed greatly with the growing sun, the inner planets have been burned to a lifeless crisp, while the atmospheres of the outer worlds have been heavily stressed.


Violent conflicts on the primary planet, between the indigenous people and the government, have been occuring ever since the first colonists arrived.  The planet is in a constant state of civil unrest as rebellions constantly try to overthrow the tyrant government.  Not helping the situation is the fact that the planet is overcrowded, far too many people for the small amount of landmass.

13 Orionis Planets

13 Orionis B (Rasul)
13 Orionis B is the innermost planet with a thick iron core.  This planet was likely always too warm to support any type of life.  The sun will eventually become a red giant which could cause the world to fall into it.

Distance: 0.69 AU

Orbit: 193 days

Temp: 402 K

Mass: 0.13 Earth

Radius: 3,561 km

Gravity: 0.41 g

Rotation: 29 hours

Moon(s): 0


13 Orionis C (Malika)
13 Orionis C
may have once had a thick atmosphere and even oceans, but is now a dry, lifeless, wasteland scorched under the growing sun.  Mining operations were established on the planet's barren surface.

Distance: 1.1 AU

Orbit: 387 days

Temp: 314 K

Mass: 0.42 Earth

Radius: 5,002 km

Gravity: 0.68 g

Rotation: 30 hours

Moon(s): 0


13 Orionis D (Calledrenus)
13 Orionis D is the primary planet, a habitable, terrestrial world covered in 90% water.  The planet's landmasses are humid, tropical, and covered in forests and jungles.  The planet's continents are small and surrounded by the global ocean.

Distance: 1.87 AU

Orbit: 857 days

Temp: 275 K

Mass: 0.87 Earth

Radius: 6,125 km

Gravity: 0.94 g

Rotation: 21 hours

Moon(s): 3


13 Orionis E (Kazim)
13 Orionis E is a small
gas giant that orbits outside the inner rocky planets.  As the sun grew larger the planet begin heating up, the once reddish clouds of methane have been turned yellow by the warming carbon dioxide.

Distance: 4.22 AU

Orbit: 8 years

Temp: 132 K

Mass: 40.75 Earth
