Echo 11 Star System

E-11 is an uninhabited star system. It was mapped by the Lorath Matriarchy and was one of the systems to be brought by the Matriarchy upon their arrival, however no colonization efforts were ever made in the system.

The system is noteworthy for being loosely parallel to Lor, due to the red star making it somewhat familiar to the Lorath.

While mineral rich the system has only one ice giant planet and no gas giants making it relatively poor in lighter elements such as hydrogen or helium.

The E-11 system is East-South-East galactic core-ward relative to the core Lorath system 7.8ly distant.

Star

Type: M6 IV Red Subgiant
Radius: 1.63 x 106 km (2.34 x sol)
Mass: 1.64 x 1030 kg (0.82 x sol)
Temperature: 2500 K
Luminosity: 2.38 x 1027 W (6.23 x sol)
Planetary Information

E-11 I

Type: Barren Terrestrial
Orbital Radius: 1.43 x 108 km (0.95 AU)
Period: 8.98 x 103 hours (1.03 earth years)
Gravity: 8.10 m/s2 (0.83 x earth)
Information: As a typical near star planet, E-11 I is more or less a large cratered rocky planet with a crust rich in the alluminium/hellenium/vulviarium/vulirarium and tungsten?Osmium?Iridium?Acorium?. It has a nearly non-existent atmosphere that contains trace amounts of nitrogen and carbon dioxide. One notable feature is a massive impact crater on the planet's northern pole.

E-11 II

Type: Barren Terrestrial
Orbital Radius: 2.19 x 108 km (1.46 AU)
Period: 1.71 x 104 hours (1.95 earth years)
Gravity: 7.50 m/s2 (0.77 x earth)
Information: Like the first planet, E-11 II is a rocky world although its further distance has enabled it to retain a thin atmosphere of carbon dioxide. The planet is 'cool' enough for its poles to retain solid carbon dioxide ice during the winter months. Its crust, while not as rich as the first planet of the system, also contains vast amounts of precursor ores.

E-11 III

Type: Garden Terrestrial
Orbital Radius: 2.86 x 108 km (1.91 AU)
Period: 2.55 x 104 hours (2.92 earth years)
Physics: Standard iron/silicate
Gravity: 11.64 m/s2 (1.19 x earth)
Hydrosphere: 80 % water
Atmosphere: Oxygen/Nitrogen Mixture
Biosphere: Full terrestrial biosphere.
Information: A lush tropical world, two major features of this planet are its vast and deep oceans and its almost total coverage of dense tropical and extra tropical forests. Its surface features four main continents (only one of which as the height to host any snow fall), and numerous archipelagos. Due to the small land mass, both poles are composed of open water leading to a fairly warm and humid atmosphere.

E-11 IV

Type: Garden Terrestrial
Orbital Radius: 4.21 x 108 km (2.82 AU)
Period: 4.55 x 104 hours (5.20 earth years)
Physics: Small iron/silicate
Gravity: 7.13 m/s2 (0.73 x earth)
Hydrosphere: 60 percent water, 5 percent ice
Atmosphere: Oxygen/Nitrogen Mixture
Biosphere: Full terrestrial biosphere.
Information: Unlike the third planet, E-11 IV is slightly farther from its star leading to slightly cooler temperatures. As a result this world's climate is more on par with that seen in temperate planets, both poles feature ice sheets with a band of tundra, temperate, then tropical vegetation leading down to the equator.

E-11 V

Type: Barren Terrestrial
Orbital Radius: 7.14 x 108 km (4.77 AU)
Period: 1.00 x 105 hours (11.48 earth years)
Gravity: 4.58 m/s2 (0.47 x earth)
Information: The fifth planet in the system is a small dusty world, its atmosphere sufficiently thick enough to support atmospheric pressure and maintained by the planet's volcanism. However the atmosphere is toxic, composed of carbon dioxide and various volcanic gases. Notable features include a large impact crater in the southern hemisphere which appears to have triggered an on going basalt flood event which continues to stain the planet's atmosphere with long trails of soot and ash.

E-11 VI

Type: Barren Terrestrial
Orbital Radius: 1.34 x 109 km (8.92 AU)
Period: 2.57 x 105 hours (29.37 earth years)
Gravity: 17.44 m/s2 (1.78 x earth)
Information: The farthest rocky body in the star system that is considered a planet, E-11 VI is for the most part… boring. A simple rocky world with no atmosphere covered in a combination of water ice, dust, and rock.
