Mystir

Mystir, also known as Aster f, is an ice giant in the Aster System. It's the fifth planet in the system. it is most known for its unique coloration. It is the last major planet of the system.
== Physical Characteristics ==
Mystir is an ice giant. It is composed mostly of elements heavier than helium. It is the smallest giant in the system. It is about 104 100 kilometers across and has a mass that of 79 Earths. A day on its equator lasts 15 hours. Mystir has an ocean made from a mixture of water, ammonia and methane beneath its thick atmosphere and it rains diamonds there due to high pressure.
== Orbit ==
One year on Mystir is 54 years. It moves around Aster with a velocity of around 8 km/s. It has a semi-major axis of around 15 AU.
== Natural Satellites ==
Mystir has 32 confirmed moons and 4 ring groups. The first eight moons are regular and orbit in practically circular orbits, while the rest are captured into irregular orbits.
=== List of moons ===
Mystir has 32 known moons, biggest of which are Pagom and Den. This is a list of all moons of planet Mystir in The Aster System.

=== Ring System ===
The ring system of Mystir possibly got formed from collisions of several moons in the planetary system that don't exist anymore. After colliding, the moons most likely broke up into many particles that could be as much as 600 million years old. The ring system stretches out from 3 650 km to 57 800 km from the equator. It consists of hundreds of rings segregated into 4 groups. From the planet outward, they are named MyR1, MyR2, MyR3 and MyR4. (MyR standing for Mystir Ring).
The rings of Mystir are also rich in propeller moonlets, which are large particles of the rings that have a significant effect on other particles.
== History and Future ==
Mystir formed about 4 billion years ago along with other planets in the system. Not much has changed since then apart from the fact that it was a much warmer planet back when Aster was still a main-sequence star. The present day rings of Mystir, as stated earlier, formed by past moon collisions in the planetary system.
Mystir will not stay in orbit around Aster forever. At some point in the future it will get perturbed by a massive object passing through the system and get ejected. Some of its moons may also pass through the Roche limit and contribute their mass to the rings.
== Colonization ==
Mystir has been left out of colonizing due to its toxic atmosphere, although there are plans for colonization of its natural satellites by the Verdan Federation.
