Wunderland is a planet circling Alpha Centauri, 4.3 light years distant, the closest extra-solar colony in Known Space's human history and as such, one of the earliest, being the longest-established human colony world. It has a surface gravity of 60% that of Earth's, a benign climate and is hospitable to human life. The system has an asteroid belt in the shape of a crescent, which gives it its name—the Serpent Swarm. The capital asteroid, Tiamat, houses one of the largest Kzin populations in Known Space.
