Minerva (Maximum Systema)

Minerva is the largest planet in the Middle Solar System.

Composition
Minerva is a rocky terrestrial planet with characteristics similar to those of the other nearby planets.It is mostly made up of Silicon based compunds, although various compounds based on various metals are also present in lesser quantities. Water ice has also been detected in varied quantities.

Atmosphere
The possibility of Minerva's atmosphere was first proposed in the 1830s, when astronomers noticed distortion around the planet when it was blocking the view of a star.

The atmosphere was confirmed in 1978, when the Voyager 1 spacecraft performed a flyby of the planet on its way to the Outer System. The atmosphere is composed primarily of Oxygen with trace amounts of Carbon Dioxide.

Surface
Minerva's surface is mainly lava plains. The exact reason behind this is currently not confirmed, but it is believed that severl large impact events late in Minerva's formation resulted in their creation.
