Treasure Planet

The Treasure Planet is the fifth planet from Pistol Star. It is an exoplanet mixed between a gas giant and a rocky planet. The Treasure Planet has a double prominent system of rings, consisting mostly of acid particles with a smaller amount of dirt and dust.

Planetary rings
The Treasure Planet is probably best known for its double system of planetary rings, which makes it one of the most visually remarkable objects in Pistol Star's planetary system.

Spokes of the rings
Until 1980, the structure of the rings of the Treasure Planet was explained exclusively as the action of gravitational forces. The Voyager spacecraft found radial features in the primary ring, called spokes, which could not be explained in this manner, as their persistence and rotation around the rings were not consistent with orbital mechanics. The spokes appear dark against the lit side of the rings, and light when seen against the unlit side. It is assumed that they are connected to electromagnetic interactions, as they rotate almost synchronously with the magnetosphere of the Treasure Planet.

Twenty years later, Cassini observed the spokes again. They appear to be a seasonal phenomenon, disappearing in the Treasurian midwinter/midsummer and reappearing as the Treasure Planet comes closer to equinox. The spokes were not visible when Cassini arrived at the Treasure Planet in early 2004.
