Tanga II

Tanga II is an ice planet in the unclaimed Tanga system, and has a surface coated with thick sheets of water, ammonia, and methane ice. When it first formed, Tanga II orbited beyond the frost line, which shifted when its star entered its red giant phase. After the red giant collapsed into a white dwarf, its temperature spiked and Tanga II began to sublimate. A trail of expelled vapor follows Tanga II as it traverses around its sun.
