How many GB is SpaceEngine?

4 GB

That makes it bigger than 59% of Simulator games we have measured.

The median Simulator game needs 2 GB; the largest tenth start at 20 GB.

Leave at least 10 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

SpaceEngine is a 3D astronomy program and game engine developed by Russian astronomer and programmer Vladimir Romanyuk. Using real astronomical catalogs and procedural generation, it creates a three dimensional planetarium representing the entire universe. Users can travel through space in any direction or speed, and forwards or backwards in time. It uses pseudo-random numbers to procedurally create any kind of planetary system, nebula or galaxy.
