Alpidra



The first of Horakameston's three gas giants, Alpidra is a large blue world orbiting at 1.0011 astronomical units from the center of the system. It is larger than Jupiter, its radius measured at 93,572 kilometers, but actually looks closer to Saturn. It has an impressive ring system approximately 280,000 kilometers across. Alpidra takes 98 days to orbit Horakameston, but its day is only 10.3 hours in length. As a result, wind speeds in Alpidra's upper atmosphere can reach 900 miles per second.

Contrary to size and appearance, Alpidra shares a composition with planets such as Uranus or Neptune. It is composed mostly of methane and ammonia, with concentrations of hydrogen, helium and oxygen. Due to the large volume of methane, Alpidra absorbs red light and appears blue. Because of this, the rings also appear to be a deep cerulean color due to the high concentrations of methane ice.

Alpidra also has seven moons, which serve as locations for most of the system's colonies. Three of these moons possess natural orbitals as well.
