Biculus Star System

Biculus is the home star of Planet Aucafidus. The star is known to humans as HD 28185. It is a yellow dwarf star similar to our sun, and is located about 128.6 light-years away from Earth in the constellation Eridanus. As far as the humans know, the star possess a long-period extrasolar planet, dubbed HD 28185 b.

There are top ten natural objects orbitting HD 28185, one belt object and nine planets in total.

1. Pixtrilis, orbits at 0.294 AU. The name means Precious. An iron-rich world with most of its mass is its iron core, probably lost most of its mantle due to collision with protoplanets on its early stage of evolution. Very rich in metal on its crusts and mantle, this planet was major source for metals on ancient time. Some historians believe that this richness in metal compounds as the source of its name.
2. Ulix, orbits at 0.529 AU. The name is Swamp, probably rooted back to some 80,000 years ago, where there is belief that the planet is covered with swamps due to its close proximity to the sun, hence hotter climate. However, rather ironically, the planet is a dry world with almost no atmosphere. A terrestrial world with thicker mantle and less metal contents compared to Pixtrilis, but still able to supply sizeable stream of metals and minerals to various places in the system in ancient times.
3. Subralis, orbits at 1.031 AU. The name means Heaven, as it is always positioned 60 degrees behind the sun as seen from Aucafidus. Some ancient religions associate it with the all seeing watcher, Mosos. Largest planet on this system, comprises about 70% of mass of the entire system excluding the star. Three of its innermost major moons had been completely dismantled to give rooms and materials for construction of its orbital ring systems, its numerous space habitats on its orbit, Gate Nexus Pontirijaris, and many more projects all around the system, including systems of orbital rings to mine gases from the surface of Subralis. Perhaps one of the most interesting spot is a dense trojan moon on its L4, Aucafidus.
4. Malaucar, orbits at 2.022 AU. The name means Forest. Its name origin is unknown, and probably lost during the Harsh Years some 70,200 years ago. An icy world outside the star's habitable zone, its surface water is frozen due to low solar illumination, but has active tectonic activity, with lots of thermal vents deep below its icy surface. Somewhat similar to Europa in this aspect, except that the heat does not come from tidal heating, but tectonic activity of this massive world.
5. Vadelatur, orbits at 2.831 AU. The name means Desert, quite self-explanatory. This planet may be considered mars-like, but it receives far less solar insulation, and slightly larger in size. Its atmosphere was a 400 mbar carbon dioxide/nitrogen atmosphere, but has been terraformed (Aucaformed) ever since.
6. Romic, orbits at 4.247 AU. The name means Hell, probably because of high concentration of dissassembler swarms on the planet. When revisited on 5,532 CL, the planet is covered with thin layer of diamond dusts. An asteroid belt object but with the size of Mars. It comprises about 90% of the entire belt mass.
7. Kodian, orbits at 6.37 AU. A superjovian planet, the name means Mercy. Perhaps it is attributed to their ancient merciful inhabitants, or perhaps the name rooted from far more ancient origins.
8. Cauki, orbits at 11.466 AU. A jovian planet. The name means Mystery, perhaps attributed to the inhabitant's eccentricity (and its planet's!) and isolationist nature. Though at modern times the inhabitants are far from eccentric, the name already stuck.
9. Pi, orbits at 21.785 AU. An ice giant. The name means Insult. At current era the inhabitants are okay with the name, but its name's origin is unknown, but some historian suggests that the name refer to the planet's powerful storms. To some terran tourists however, the name curiously fits its mass to radius ratio, that is 3.14!
10. Aquatio, orbits at 31.589 AU. Another ice giant, the name means Patience. Meanwhile most terran tourists believe that the name refers to its ocean blue surface!
