Sarvannia is the second planet in a three planet solar system with a red dwarf star. The inner planet is a small rocky planet that is almost as red as Mars. It is void of all life, has almost no atmosphere, and has an average temperature of about ten degrees Fahrenheit (negative twelve degrees Celsius). It has a circular orbit and is about twenty-eight degrees bigger than Mars. The outer planet is a green gas giant about thirty percent bigger than Uranus and has beautiful golden rings. It has a circular orbit, a thick and cloudy atmosphere, and an average temperature of about negative three-hundred twenty degrees Fahrenheit (negative one-hundred ninety-five degrees Celsius).
Almost twice the size of Earth, Sarvannia has an elliptical orbit that at its closest point to its sun also brings it close enough to the inner planet to easily see it within the night sky. Average temperatures range from negative two degrees Fahrenheit (negative nineteen degrees Celsius) at its closest point to its sun to negative one-hundred sixty degrees Fahrenheit (negative one-hundred six degrees Celsius) at its farthest point. Its atmosphere is mostly made up of water, oxygen, nitrogen, and carbon dioxide. However, because of how cold Sarvannia is almost all fresh water on or close to the surface is frozen solid year-round.
Their calendar year consists of four-hundred days, which are split up into ten months of forty days each. Only one month of the year is summer time, due to the slingshot effect of its elliptical orbit. Spring and autumn lasts two months each, and winter lasts five months. Because of its elliptical orbit it is the same season across all of Sarvannia, only altering in severity depending on your location. Each month has four weeks of ten days each, and each day has thirty hours. Unlike Earth, they do not count the hours in minutes or seconds. Instead, each hour is split into ten parts. So what we would call an hour and a half here on Earth, for example, would be stated as one-point-five hours on Sarvannia. Also unlike Earth, the days of the calendar year run from sunset to sunset, which is averaged at the equator. The first hour of the day is called hour one and the last hour of the day is hour thirty.
Sarvannia’s solar system is very close to the center of its galaxy, and once every hundred years a black circle void of any light will appear in the night sky. This is because everything has aligned so the black hole in the center of its galaxy is visible from Sarvannia. During this phenomenon an extra week is added to mark the new century, as it takes about that long for this black circle to pass across the sky and eventually vanish. This also makes up the difference between their calendar year and planetary year over the previous century.
Unlike Earth, two moons orbit Sarvannia. Probably their most unique characteristic would be the fact that they share the same orbit. Always opposite of each other, they take turns ruling the night sky. The smaller of the two moons is very similar to Earth’s moon. The only noticeable difference is it has a lot more of a silver shine to it than Earth’s does. Therefore, it is rightfully called Silver Moon. The second moon is about twice the size of its smaller counterpart and appears blood red in the night sky, especially when it is full. Its most common name is Blood Moon. However, there are a few cultures on Sarvannia that call it Mother Moon.
