Taranis - LouisB3/Grannus-Expansion-Pack GitHub Wiki
Description
Taranis is a rocky planet orbiting very close to its parent star. Its two hemispheres stand in stark contrast; the sun baked side hot enough to melt rock, the other side frozen in perpetual darkness. Any encounter with this tiny world is certain to be a high-speed affair. If you plan to stay be sure to pack plenty of delta-v, as well as sunblock.
