KG-348 (Earth-7149)

KG-348 is a Jovian gas giant in the Procion system, with layers that mostly consists of molecular hydrogen. It is home to a series of cloud layers that form an unorthodox mixture of metallic gases and the standard helium-3. It was orbited by Seegson's Sevastopol Station.

History
In 2564, Sevastopol Station's Project-348 laboratories, from the Gemini Exoplanet Solutions, were jettisoned from the space station into KG-348, where it burned until it exploded, in order to kill the Stalker, a xenomorph Drone that slaughtered most of the station's population, which they successfully did after Amanda Ripley-McLaren sealed the module with the creature inside.

Later, the Anesidora was destroyed, next to Sevastopol, which damaged the space station's gravity stabilizers and leading it to fall into KG-348, where it was destroyed once it burned up in the atmosphere.
