How many GB is Interastra?

15 GB

That is more than the typical Simulator game, which needs about 4 GB.

Leave at least 23 GB free: games need headroom to unpack updates.

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

Interastra is a fully immersive science fiction survival adventure game set in outer space. Discover unknown planets differing in weather conditions, gravity, and resources. Craft necessary equipment, launch and control space rockets, explore the universe and survive among the stars.
