Palsa

Palsa, also known as Etra c, CelWP M2 c, or WI 135643 c is the smallest and last planet around the neutron star Etra. It is a small, hot rocky planet and was added in Release 7.

Physical Characteristics
Palsa is a super-mercury, a planet similar in composition to mercury, but larger. It has no atmosphere, so it is pockmarked with craters. Palsa is a mostly uniform dark gray color, possibly with a slight bluish tint, with no contrastive albedo features. Palsa, with a mass of just 0.1 earth masses, and orbiting far interior to the habitable zone, and around a freaking PULSAR, is an extremely unlikely terraforming candidate.

History
During the colonization and terraforming of Taminar, some spacecraft left the system in search of more resources. One of the survey craft, the Spacetrotter-14, flew by Palsa and recorded significant amounts of heavy metals in the mapped area. A large mining colony was later built, and here we are today.
