System Data[edit]

Velovo-Jirune Systm[edit]

The primary is Velovo, a dim red main sequence star. It has a luminosity of 0.004 Sols, a mass of 0.273 Sols, and a diameter of 414,000 km. (I) a trace atmosphere radworld, (II) a sparse stony planetoid belt, (III) Hasa, a ringed large gas giant: Jurune is its outer moon and is designated the mainworld, (IV) a dense icy planetoid belt, (V-I) an exotic atmosphere bigworld, (V-II) a trace atmosphere iceworld, and (VI) a vacuum worldlet form the outer system. Many of the worlds retain satellites.

(III) Hasa[edit]

(III) Hasa is a ringed large gas giant that orbits Velovo at a mean distance of 0.82 AU (122.7 million km), within the outer system, and has an orbital period of 1 year 154 days. It has a diameter of 133,000 km and an atmosphere consisting of 91% hydrogen (H2), 9% helium (He), and less than 1% methane (CH4), carbon monoxide (CO), ammonia (NH3), water vapor (H2O) and other trace gases. It is a brown-tan color with broad pale bands, with a number of large semi-permanent equatorial storms. It retains a family of three major satellites.

Satellites[edit]

Hasa retains three major satellites:

(IIIr) Ring System (UWP YR00000-0, extending to 2 Diameters/265,000 km)
(IIIa) Malasa (UWP Y101000-0, orbiting at 6 Diameters/800,000 km)
(IIIb) Jirune (designated the mainworld, orbiting at 11 Diameters/1.45 million km)
(IIIc) Inik (UWP Y4A0000-0, orbiting at 13 Diameters/1.73 million km)

Mainworld Data[edit]

(IIIb) Jirune[edit]

(IIIb) Jirune is the second of the three major moons of (III) Hasa and is designated the mainworld. It orbits its parent world at a mean distance of 11 diameters (1.45 million km), with an orbital period of 134 days 1 hour: it is tidally locked to Hasa. The axial tilt is 4 degrees relative to Hasa. Jirune has a diameter of 3,016 km, a density of 5.88 g/cm³ and a surface gravity of 0.25 G. Tidal stresses generated by the gravitational pull of Hasa cause occasional geological activity. The atmosphere is rated as Vacuum. Around 18% of the surface is covered in sheets of water-ice. Mean surface temperature: -135°C.

Mainworld Geography and Topography[edit]

Total surface area: 28.6 million km², Land surface area: 23.5 million km², Ice surface area: 5.1 million km².
