The Leonis Systems is the common term used to refer to various colonised star systems beyond the edge of governed space located within the greater Leo Constellation. Owing to their closeness and low ship traffic, the systems have historically been popular with Kimber Racers and corporate prospectors.

Stars[edit | edit source]

The two closest stars within Leo include CN Leonis (Wolf 359) and AD Leonis (Gliese 388) with their distances from Earth being 7.9 and 16 light years respectively, and from one-another by 8.741 ly.

CN is a cool star with a mass roughly equivalent to 9% of the Sun's, with its mass and temperature being at the lowest limit at which a star can perform hydrogen fusion. Its luminosity is only 0.1% of the Sun's, being so dim that its brightness is comparable to that of Luna.

AD is a flare star that undergoes random increases in luminosity and caution is advised during transit throughout the system due to the unpredictable solar activity.

The stars have a visual magnitude of 13.54 (CN) and 9.43 (AD), and are both not visible from the Solar System with the naked eye.

Planets[edit | edit source]

CN Leonis bears two planets, CN Leonis B and C. B is a small gas giant of 43.9 Earth-masses that bears a number of thin rings of rock and ice dense enough to be visible if they were in Solar light. C is a rocky super-earth of 3.8 Earth-masses that is home to an an Axil Industries mining operation that ships out the mineral resource to the Commonwealth of Earth and the Zhu Que Directorate. Its closeness to Proxima Centauri (at 8.291 ly) has also attracted the attention of its controlling conglomerate Proxian Credit, which aggressively competes with the two Interstellar States for the system's wealth.

AD Leonis is home to a single planet, AD Leonis b, a hot gas dwarf of approx. 6 Earth masses that sits within the active solar zone. Scout probes have indicated a wealth of mineral resources in the form of asteroids caught in the gravitational well of the star and the gas giant, which has caught the attention of Axil Industries. AD's closer proximity to the Luyten System (11 ly) than that of the Solar has also earned it notable favour from Zhu Que.
