Epsilon Indi

 

Epsilon Indi is a planetary system orbiting a orange K-class star.  The system lies in the Indus Constellation of the Inner/Sol Region.

 
Epsilon Indi is located only 11.8 light years from Earth, it is one of closest habitable systems to Earth.  Epsilon Indi A is a main sequence star that is orbited by a binary brown dwarf system (Epsilon Indi Ba/Bb) at a distance of almost 1500 AU.

 

Epsilon Indi's primary planet is Indra.  Despite its closeness to Earth, colonizing Indra was a slow process.  The planet is covered in various mosses and lichens, the planetary winds blow spores across much of the surface.  When breathed in by unacclimated humans, the spores can cause severe allergic reactions.  The planet also has a thick atmosphere with lower oxygen than Earth, making it difficult to breath if the human body hasn't been adjusted to the conditions.

 

The planet's environment made any large-scale colonization efforts impossible, because it takes many years to acclimate to the environment.  Due to the these factors, the majority of Indus's population was born on the planet, rather than immigrating there,

Epsilon Indi Planets
       

Rudras (Epsilon Indi Ab)
Epsilon Indi Ab (Rudras) is a dry warm world that orbits on the inner edge of the habitable zone.  The planet has a thin carbon monoxide atmosphere.  Due to its inner orbit, Rudras has potential to be terraformed, though it would likely be difficult because if the atmosphere is thickenedm, the planet could get too warm for liquid water.

Distance: 0.38 AU

Orbit: 97 days

Temp: 325 K

Mass: 0.37 Earth

Radius: 4597 km

Gravity: 0.71 g

Rotation: 79 hours

Moon(s): 0

       
       

Indra (Epsilon Indi Ac)
Epsilon Indi Ac (Indra) is a partially habitable terrestrial world.  Indra's surface is covered in a large landmass with an extensive system of inland seas.  The land areas are covered in mosses and lichens, giving much of the land an overall green color.  The spores from the mosses can be poisonous to non-native humans

Distance: 0.72 AU

Orbit: 258 days

Temp: 290 K

Mass: 0.7 Earth

Radius: 5669 km

Gravity: 0.89 g

Rotation: 34 hours

Moon(s): 1

       
       

Saranyu (Epsilon Indi Ad)
Epsilon Indi Ad (Saranyu) is a massive gas giant with almost 3 times Jupiter's mass.  The planet's cloudy atmosphere is a mixture of hydrogen, helium, methane, and ammonia.

Distance: 12.82 AU

Orbit: 52.6 years

Temp: 47 K

Mass: 2.71 Jupiter

Radius: 83465 km

Gravity: 5.01 g

Rotation: 19 hours

Moon(s): 27

       
       

Epsilon Indi Ba/Bb
Epsilon Indi B is a binary brown dwarf system that orbits Epsilon Indi A at a distance of almost 1500 AU.  The browns dwarfs are separated by an average distance of 2.1 AU.

Distance: 1459 AU

Orbit: 63,953 years

Mass: a-51 Jupiter

Mass: b-28 Jupiter
