Tsanfau II is the second-largest moon of Tsanfau. It is about 690 kilometers (428 mi) in diameter. Tsanfau II is mostly covered by freshly created and relatively clean ice sheets, exposed rocky mountaintops, old craters, ice scraps, ice geysers, water-ice layers, and a surprisingly dense atmosphere for its size.
