Your Universe Awaits
There are 18 quintillion planets in the game. Even if each planet was visited at a rate of one per second, it would take five billion years to explore them all – by which the Sun in our solar system would have burnt out, essentially giving the game a near infinite number of worlds to explore!
To help guide players through such a vast number of locations No Man’s Sky has an overarching goal of reaching the centre of the universe, where there are more bountiful resources and more challenging locations to discover. This, however, is just a guide, and players are free to explore the game however they like.
