Coloria Planetary Physics

'''This page is a work in progress! More, and more detailed information will be regularly added.'''

What we consider “the planet of Coloria” is actually a large moon of a gas giant. Keep this in mind when worldbuilding and culture building! For the sake of this project, the moon is habitable, with general climate similar to earth. There are two other moons in orbit of the gas giant (tentatively called Iris and Arcus), but far enough away that their gravity does not affect Coloria.

Each sidereal day (full rotation of the moon on its axis) on Coloria is equivalent to 24 earth-hours. There are about 33 days in one month (it takes 32.7 days for the moon to revolve around the gas giant). There is an eclipse every month for 14.6 hours as the gas giant aligns directly between the sun and the moon. There are 60 months in a year (full revolution of the gas giant and its moons around the sun).

Similar to earth, there are two primary seasons experienced in tropical and subtropical regions (ie. rainy/dry) and at the poles (ie. long day/long night), and four seasons experienced in temperate and subarctic regions (ie. spring, summer, winter, fall). Due to the orbit around the gas giant, each month Coloria also experiences slightly warmer days and slightly cooler days.

Coloria has a total world population of around 340 million sentient individuals. The population density and distribution varies by country, culture, and species. There are beings that live in areas considered uninhabitable by humans.

Coloria’s sky is a slightly more saturated blue than earth’s. The sun is whiter than ours with a blue hue instead of a yellow one. It appears in the sky about 70% the size of earth’s sun, similar in size to a fingertip held at arm’s length. The gas giant appears in the sky about 13x the size of earth’s moon, similar in size to a palm held at arm’s length. The foliage of the planet is predominantly violet and yellow-green.
