Krypton Comet 2017

Comet P/24445 OV3 This unusually massive comet that contains large amounts of solid Krypton, and is only structurally sound in deep space at temperatures below 100 Kelvin. Initial scans of impact craters on its surface suggested residue of the crystalline structures necessary for Walking Simulator Pods. A small research station was established, but quickly abandoned when more detail scans came back negative. At the time of your arrival, P/24445 OV3 is passing near the rings of an exoplanet, which will redirect its course towards a nearby star, causing its destruction within a few years.
