ASTRO

An endless, real-time universe you can fly through.

Every star, planet, moon and galaxy is generated from a seed. Pick something in the sky and the autopilot takes you there. Land on it, orbit it, or just look at it. Nothing is loaded from a file, and no two worlds are alike.

What you can do

• Fly from a planet’s surface out to other galaxies, with no loading screens
• Click any object to open its info panel: a live 3D view you can turn, plus real values for size, mass, orbit, climate and more
• Search by name or paste a seed to share a place with someone else
• Change the time rate, run time backwards, and watch the orbits and the light move
• Play with keyboard and mouse, gamepad or touch
