System Data[edit]

Ease-Erena System[edit]

The primary is Ease, an ordinary white main sequence star. It has a luminosity of 4.42 Sols, a mass of 1.38 Sols, and a diameter of 2.031 million km. The inner system consists of (I) a vacuum worldlet, (II) a very thin atmosphere inner world, (III) a corrosive atmosphere inferno world, and (IV) a dense atmosphere stormworld. (V) Erena orbits within the habitable zone and is designated the mainworld. (VI) a small gas giant, (VII) a dense rocky planetoid belt, (VIII) a large gas giant, (IX) a trace atmosphere iceworld, and (X) a small ice giant form the outer system. Most of the worlds retain satellites.

Mainworld Data[edit]

(V) Erena[edit]

(V) Erena is designated the mainworld and orbits Ease at a mean distance of 1.71 AU (255.8 million km), within the habitable zone. It has an orbital period of 1 year 330 days and a rotation period of 19.5 hours. The axial tilt is 16.5 degrees. Erena has a diameter of 16,388 km, a density of 5.97 g/cm³, and a surface gravity of 1.39 G. The world is geologically active. Its atmosphere is rated as Dense, with a mean surface pressure of 2.33 bar and a composition of 79% nitrogen (N2), 20% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), ozone (O3), neon (Ne) and other trace gases. Approximately 54% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.25m. Mean surface temperature: 24°C. The climate is rated as Temperate-Warm and experiences minor seasonal changes during the local year. The atmosphere is extremely active and violent weather systems, driven by the star and the seas, scour the globe.

Satellites[edit]

Erena retains two natural satellites, a cratered vacuum worldlet named Detso and an exotic atmosphere hospitable world named Vuro:

(Va) Detso (UWP YS00000-0, orbiting at 9 Diameters/145,000 km)
(Vb) Vuro (UWP G5A2365-9, orbiting at 45 Diameters/740,000 km)

Mainworld Geography and Topography[edit]

Total surface area: 844 million km², Water surface area: 456 million km², Land surface area: 388 million km².

Native Lifeforms[edit]

Ease-Erena System[edit]

The hot marginally hospitable stormworld lying in orbital position (IV) (within the H– region of the inner system) has primitive extremophile native life, consisting entirely of microscopic cyanobacteria-parallels that thrive in the extremely harsh conditions.

Erena, the mainworld, has extensive, abundant native life, with complex organisms inhabiting every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

No other world in the system is known to have native life.
