Marcorius

Marcorius is the 2nd planet in the Blox Centari System, with it having a very hot environment resulting in the planet being nothing more then a rocky crater filled landscape, with the place being hot enough to melt lead.

History
Marcorius formed around the same time as Mercury did, similar to mercury it has little atmosphere, and features, but unlike mercury it shows signs of what used to be volcanoes, and lava flows.

Present Day
The RSA has discussed sending a exploration rover to Marcorius to see what makes it up, and what it hides, but these discussions have been turned down due to the risk of the rover's electronics possibly short circuiting, and making the rover trapped on the planet due to the extreme heat.
