Torphen (Celestial Classification HD-044P4) is a mountainous terrestrial planet and the fourth planet in the Nethierre star system, located in the North-Eastern section of the Human astral territory. Positioned around 0.048 astronomical units away from the red dwarf star, it completes one full orbit every 319 hours. Torphen's nature as a tidally locked body means its rotational period lasts the same amount of time. A lack of liquid surfaces combining with some disruptive geological activity has prevented life from evolving.

The harsh conditions on Torphen have prevented long-term settlers from residing on its surface. However, its high metal content means there are frequent mining expeditions sent in to retrieve valuable materials. There are no known Soup deposits.
