Rigel XIII, also called Lonakar, was a planet, the thirteenth planet of the Rigel star system. Rigel XIII was a large class J gas giant, a superjovian world that was almost a brown dwarf. This planet had a unique anomaly—a superstring twisted into a Moebius configuration, rotating and spinning in place above the south pole, at a distance of 100 million miles. Major sunspot activity on Rigel B caused the anomaly to "flare up", opening a temporal anomaly at its center, likely a rift between two points in space-time. Fortunately, it was far enough away from the heavily used space-routes around the Rigel system for safety.
