Geminora is a yellow g-type star 330 light years from Earth.  Geminora is the located in the Betelgeuse Region of the Inner Sphere.


Geminora is home to an ancient society over 2000 years old.  Thousands of years ago an advanced, space travelling society called the Athenians developed on Earth.  They left Earth taking their technologies with them and seeded colonies using human embryos on thousands of planets.  One of the colonies the Athenians seeded was Geminora.  Over the centuries Geminora grew from a small Athenian colony, to a technology advanced planet home to billions.


Throughout its history, Geminora has been largely peaceful, free of wars and violence that plague the majority of human controlled planets.  The Geminora people believe in peace and pacifism, they believe in balance with nature and industrial needs.  This balance has allowed their planet to stay beautiful even with a swiftly growing population.

Geminora Planets

Geminora B

Geminora B
Planet B is a hot dry world sitting close to the star.  The planet lacks and atmosphere, its cratered surface is composed mostly of iron and sulfur.  The planet is still geologically active, causing occasional volcanic activity to occur on the surface.

Distance: 0.36 AU

Temp: 540 K

Mass: 0.26 Earth

Radius: 4122 km

Gravity: 0.61 g

Rotation: 29 days

Geminora C

Geminora C
Planet C is a warm world with a thick carbon dioxide and nitrogen atmosphere.  Surface tempertures under the greenhouse gasses can reach 200 C, making the surface extremely hot.

Distance: 0.89 AU

Geminora D

Geminora D
The primary planet is an earth-like world orbiting the sun in 521 Earth days.  Water covers 65% of the planets surface, the land areas separated in 3 continents: Electra, Maia, and Alcyone.  Maia and Alcyone are northern and southern continents, covered partially in ice.  Electra is the largest continent roughly centered across the equator.  The majority of the population live on Electra.

Distance: 1.27 AU
