Mann is an ice planet that orbits the black hole Gargantua. The planet is named after the first astronaut to land there named Dr. Mann.
The planet was first visited by Dr. Mann, ten years prior to the launch of Endurance. Upon arrival, Mann realizes his planet was uninhabitable. With his robot companion KIPP, they dropped probes at nearby locations with the hope of finding a rocky, habitable surface, below the frozen clouds they stood on.
