Rogue Planet

From publisher blurb: This is an adventure for Cepheus Engine. A rogue planet has been discovered traveling through the Sonora sector. So far it has not collided with any other worlds in it's path. Scientists and astronomers are alarmed at it's arrival and have many questions. How did it get here? Where did it come from? Is there an atmosphere? Is anyone alive on this world? Was there ever? A scientist offers to hire the travelers to visit this world and explore it.
