Aston - Universe sandbox/ Space Simulation game
A downloadable game for Windows and Linux
ASTRON
Astrophysics Sandbox
Astron is a Advanced 2D space simulator where you can throw planets, stars, and black holes together to see how orbital gravity behaves (or crashes). I built this to let you easily design stable stellar systems, watch gas clouds burn, and mess around with orbits in real-time.
Orbital Presets
If you don't want to build from scratch, you can load pre-configured templates.:
Features
- Spawn Anything: Place custom rocky planets, massive gas giants, stars, or black holes. Click and drag to set initial velocity vectors.
- Interactive Gas Clouds: Stellar gas/nebulae erode and change color smoothly as hot stars pass near them, lighting up HII ionization zones.
- Control the Simulation: Speed up time, freeze physics, toggle collisions, enable visual gravity grids, and customize trail lengths.
- Space Soundtrack: Includes sequenced ambient tracks.
- Settings Panel: Fully categorized panels to tweak physics constants, visuals, etc.
Quick Keyboard Controls
