Moonmus
The Mun, is a large satellite orbiting Asyur. It is mostly gray in appearance, with craters of various sizes dotting its otherwise smooth surface. The Mun’s discovery is widely regarded as one of the more important breakthroughs of Asyur's cultural evolution. Granted, it happen all that time ago; it’s still fair to say Asyur's Races are wiser and more evolved now than they were back then.''Moonmus, also known as the Mun and sometimes written as Mün, is a relatively large moon orbiting Asyur. It can be thought of as an analogue to Earth's own moon, which frequently is simply called “the Moon” (Latin: Luna). It is gray in appearance with craters of various sizes and mountains exceeding 5029 m in height. The gravitational pull on the surface is 1.63 m/s², approximately 5/6 and 8.18 m/s² lower than that of Asyur and about the surface gravity of Earth's Moon (1.624 m/s²). It is possible to land on the Mun or use it for gravity assist (gravitational slingshots) to outer bodies such as Minmus or into Asyur orbit, though such maneuvers do not save very much fuel and are more imprecise. It is, however, useful for plane changes with proper timing. There are anomalous geological formations that can be found on the surface of the Mun. Synchronous orbit around the Mun is not possible, since it would have to occur at an altitude of 2 970.58 km, beyond the Mun's sphere of influence. However, putting your spacecraft just outside Mun's SOI and having the same semi-major axis would make it appear stationary. A normal 25 km orbit can be achieved using around 800 m/s delta V. A semi-synchronous orbit with half the rotation period of the Mun is possible at approximately 1797.41 kilometers.
Geography
The Mun's terrain is rough, grey, and scarred by craters. Its low-lying areas tend to be darker in colour. The Mun also features canyons which can be hundreds of meters deep and a few kilometers long.
The Mun's highest points reach a maximum altitude of more than 7061 m near the south pole at 152.33° W and 82.52° S. Its lowest point, below -247 m, is on the northern hemisphere south-west of the large northern crater at 76.63° W and 35.32° N.
Localized Phenomena
The Space Kraken has been encountered on the Mun, with objects being thrown out of Asyur's sphere of influence by their anomalous powers.
