Astronomy studies events and objects on a cosmic scale. Gravity Simulator makes these concepts tangible to the extent that students can directly manipulate planets, moons and orbits, observing their interactions and effects on each other.


Physics of planetary proportions are hard to grasp. The effects of gravity, for example, are evident in everyday life, but understanding its actual impact on our universe is tough without a simulation as a reference point.


Creative thinking may seem out of place in a simulator game about gravity, but the reality is different. Gravity Simulator visualizes every single trajectory and paints beautiful pictures across the pitch black canvas of space.
