Characteristics

Auria is a class TFI moon. The gas giant it orbits, Aleth, is the second planet from a G2-class star, and orbits at 0.98AUs.

Size

Auria has a mass of 0.9 Earth masses, and a diameter of around 13500km. As such, its density is around 0.76 times Earth's, and its surface gravity is 0.8G.

Composition

Auria's crust is 46.2% oxygen, 26.5% silicon, 8.2% iron, 4.8% aluminium, and the remainder other metals and elements.

Surface

The surface of Auria is 70% water and 3.4% ice. The global average surface temperature is 19.7 degrees centigrade, though it can be 30 degrees at the equator and reach -10 degrees at each pole.

Atmosphere

Auria's atmosphere is 76.6% nitrogen, 22.5% oxygen, and the remainder mainly argon. The pressure at sea level is 0.9 bars.

Rotation

Auria takes 21.9 hours to rotate on its axis. It has a stable axial tilt of 17 degrees.

Biosphere

Auria's biosphere is rich and diverse. The majority of the land area is covered by forest, which is green-coloured at the equator but becomes shiny and gold-coloured in the temperate regions.

There are fern- and grass-analogues, as well as a moss-like plant which is symbiotic with a fungus and grows over most rocks and mountains.

There are two dominant animal groups. One has no limbs, but usually serpentine or vermian forms. The other is a group of tetrapod-analogues. Both live in the land and in the sea.
