Our take on Planetarium 2 - Zen Odyssey

The defining detail is the physics sandbox: planets, asteroids, and everyday objects can be repositioned, resized, and sent into collisions while custom solar systems are assembled.

What is Planetarium 2 - Zen Odyssey?

Planetarium 2 - Zen Odyssey is a physics-based space simulator centered on an open-ended astronomy sandbox.

It lets players explore the solar system, exoplanets, galaxies, black holes, probes, satellites, and planetary surfaces. Custom solar systems can be made by adding or removing planets, changing orbital properties, scaling objects, and triggering collisions. Planets can be changed through temperature adjustments, vegetation, clouds, water, rings, asteroid belts, and population settings, with procedurally generated planet variations. Rockets, landers, and rovers support travel to planetary bodies, while the International Space Station can be explored in an astronaut role. The simulator also features solar flares, pulsars, gravitational waves, auroras, weather effects, and eclipses.
