Oasis

Oasis

Oasis is a marginally habitable world orbiting Omicron2 Eridani A. It is on the inner edge of the habitable zone of this system. Its equator is too hot to be habitable. The only habitable region of this planet is around the small ocean at the south pole. This ocean covers only three per cent of the planet and is extremely saline. Oasis is a small world with a radius only about three-quarters of Earth’s.

Oasis has a slow rotation, with a day equal to slightly more than two Earth standard days and a small axial tilt. The residents of Oasis find the slow rotation inconvenient but not especially so. Like the residents of Polonius, the residents of Oasis use an artificial day that is half the length of the natural day and are quite used to the idea of every second “day” being dark.

With the low axial tilt, there are no perceptible seasons on Oasis. With no seasons, the calendar of Oasis does not need to follow the motion around its local sun. Instead, the Oasis calendar uses a simple 336-day calendar with 12 months of 28 days each, being very similar to the Aridian Fixed Calendar but with different month names. The length of the Oasis calendar year is very close to the length of Earth’s calendar year, being only about 0.7% longer.
