System:Oronusiil

Overview
Oronusiil is a large yellow main-sequence star located at angle: 138.60° distance: 8,503.76pc. It is the home system of the Oronusian Elatti empire, and subsequently their main base of operations and seat of their high council.

At 4.97 billion years old, Oronusiil is approximately at the halfway stage in it's life cycle, with another 4-5 billion years of life left before it goes supernova. It's stellar classification is G5V.

Aquinisiil
Aquinisiil is a large gas giant situated 197,054,721 km from Oronusiil, it is the outermost planet and is also the only gas giant in the Oronusiil system. It is approximately 3 times the size of Oronus, with a surface area of 1,366,566,43 km². A recent study of the atmosphere has indicated high quantities of gaseous hydrogen, sulphur and phosphoric acid, and also a trace amounts of water vapour. Aquinisiil has a small core with a surface area of only 176,879km², in this respect it is smaller than Oronus.

Aquinisiil is one of the most prominent features in the Oronusian sky and can be seen throughout most of the year. The discovery of Aquinisiil dates back to well before the earliest known records and was one of the first named objects by sentient Oronusians. Ancient philosophers were always speculating on its size, with some predicting it could be 200 times as massive as Oronus and some giving more accurate sizes.
