System data

The primary is Vush, an ordinary white main sequence star. It has a companion, Landax, a dim red subdwarf, lying 890 AU distant. Vush has a luminosity of 4.42 Sols, a mass of 1.38 Sols and a diameter of 2.032 million km. The inner system consists of (I, II) two rocky vacuum worlds, (III) a trace atmosphere world, and (IV) a large exotic atmosphere world. (V) Uffan orbits within the habitable zone and is designated as the mainworld. (VI, VII) two large gas giants, (VIII) an exotic atmosphere world, and (IX) a dense icy planetoid belt form the outer system. All of the gas giants and many of the rocky worlds retain families of satellites.

Companion System

The companion is Landax, an ordinary red subdwarf star. It orbits Vush at a mean separation of 890 AU. It has a luminosity of 0.0074 Sols, a mass of 0.134 Sols and a diameter of 399,000 km. (I) a rocky vacuum world and (II) a small gas giant form its planetary system: all lie within the outer zone. The gas giant has a spectacular ring system and retains a single large satellite.

(III) Uffan

(III) Uffan is designated as the mainworld. It orbits Vush at a mean distance of 1.6 AU (241 million km), it has an orbital period of 629 days 6 hours and a rotation period of 37.3 hours. The axial tilt is 2 degrees. Uffan has a diameter of 13,052 km, a density of 5.47 g/cm³, and a surface gravity of 1.01 G. It has an atmosphere rated as Standard, with a mean surface pressure of 0.99 bar and a composition of 76% nitrogen, 23% oxygen, and 1% argon, carbon dioxide, neon and other trace gases. Approximately 64% of the surface is covered in oceans of liquid water: average tidal ranges are around 0.1m. Mean surface temperature: 21°C. The atmosphere is dynamic and weather systems, driven by the star and the oceans, roll across the globe. The climate does not have seasons and the weather follows patterns caused by geographical factors.

Mainworld Geography & Topography

Total surface area: 535 million km², Land surface area: 153 million km², Water surface area: 253 million km².

Small continents, and many large islands and archipelagos. Much of the land mass is concentrated around the equator and the temperate zones. Minimal tides.

Native Lifeforms

Extensive native life.

The world where Horvath's Ponies were first bred.
