| - The Wotan system comprises of the star Wotan and the objects that orbit it. Of the objects that orbit Wotan, the four largest are the planets, forming the planetary system around the star. Other smaller objects that orbit Wotan are asteroids, dwarf planets, and comets. Believed to have been formed approximately 4.3 billion years ago, the Wotan system has four planets, which in order in line outwards from the star are Thor, Middan, Tyr, and Loki. Of the four, Thor, Middan, and Loki are all terrestrial planets composed of a solid rock surface with thin atmospheres, whereas Tyr is a gas giant composed of a thick atmospheric layer made up primarily of helium and hydrogen. Only Middan rests at a distance from the star Wotan where life can exist at the formation of vast oceans of liquid water. All planets have almost circular orbits that lie within a nearly flat disc called the ecliptic. Smaller objects also exist within the Wotan system. A belt of asteroids separates Tyr from Loki, composed mostly of objects made up of rock and metal, although much smaller than the planets in size. Objects similar to asteroids also orbit Wotan beyond Loki, though they exist in a mass surrounding the entire system rather than in a cohesive ring. Among both the asteroid belt and the asteroid cloud are objects which are round and able to emit their own gravitational fields, although they are much too small to be considered planets, and as such, are known as dwarf planets. In addition to asteroids and dwarf planets, comets, long-orbiting masses of primarily ice and rock, have orbits around Wotan which are not circular as the orbits of most bodies in the system are, and as such, their appearance in the system varies greatly in both time and location. Smaller bodies also orbit the planets themselves, known as moons.
