System Data
Urshin-Lerant System
The primary is Urshin, an ordinary orange main sequence star. It has a luminosity of 0.352 Sols, a mass of 0.774 Sols, and a diameter of 1.168 million km. The inner system consists of (I) a vacuum worldlet, and (II) a corrosive atmosphere inferno world. (III) Lerant orbits within the habitable zone and is designated the mainworld. (IV) a ringed large gas giant, and (V) a small gas giant form the outer system. Many of the worlds retain satellites.
Chush Subsystem
The companion is Chush, a red subdwarf star that orbits Urshin at a mean distance of 45.3 AU (orbital position (X), 6.8 billion km) and has an orbital period of 346 years 204 days. It has a luminosity of 0.011 Sols, a mass of 0.154 Sols, and a diameter of 256,000 km. (I) an exotic atmosphere bigworld, (II) a vacuum iceworld, and (III) a ringed small ice giant form the outer system. Many of the worlds retain satellites.
Mainworld Data
(III) Lerant
(III) Lerant is designated the mainworld. It orbits Urshin at a mean distance of 0.59 AU (88.3 million km), within the habitable zone. It has an orbital period of 188 days 4 hours and a rotation period of 18.5 hours. The axial tilt is 19 degrees. Lerant has a diameter of 6,623 km, a density of 5.02 g/cm³, and a surface gravity of 0.47 G. The world is geologically active. Its atmosphere is rated as Thin, with a mean surface pressure of 0.63 bar and a composition of 77% nitrogen (N2), 22% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. Approximately 41% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.2m. Mean surface temperature: 33°C. The atmosphere is active and strong weather systems driven by the star and the seas drive across the globe. The climate is seasonal.
Satellite
Lerant retains a single natural satellite, a tiny vacuum worldlet named Menter:
- (IIIa) Menter (known UWP ?S00???-?, orbiting at 4 Diameters/27,000 km)
Mainworld Geography and Topography
Total surface area: 138 million km², Land surface area: 81 million km², Water surface area: 57 million km².
Native Lifeforms
Lerant, the mainworld, lying within the habitable zone, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.
