Munakay PZ724 is one of four planets in the star systemOkbegraf on the PC version of No Man's Sky universe.
It's been a while since I discovered my last planet with a cold biome. But this one here is a great example. It's by far the coldest world I've been on so far (meanwhile displaced by Hoshinoharak in the Bondvi-Elt III-System) with temperatures well around 100 degrees below the freezing point of water (Celsius). Exploring is a little bit of a pain here, so I stopped when I found five out of the nine animal species. Oddly, three of them were rare, one of them being among the most disgusting creatures I ever came across. The appearance of the planet is mostly white of course, with red rocks and green vegetation. It's also mentionable that this planet is a source of the element Radnox as seen in the picture below.
