Download of the day – Planetarium

Planetarium, as its developer is keen to point out, isn’t a game – it’s a planet generator – but it’s great fun to tinker with. 

You can make your own planet using the small selection of controls, but the real fun is in discovering the 250-odd planets it already contains. These can be found by typing  words into the search box at the bottom right, then tapping Enter to see what appears. Move your mouse over the planet – if you’ve been lucky, you’ll see a description written by the planet’s creator.

The Planetarium Subreddit contains a list of planets discovered by players. If you find something interesting, you can take a screenshot by tapping 4 on your keyboard. Planetarium is only available for Windows at the time of writing.
