Orbiter is an open-source space flight simulator based on Newtonian mechanics, letting users pilot historic, hypothetical, or fictional spacecraft across the solar system. It is a free-form sandbox with no predefined missions, focused on realistic orbital mechanics like ascent, rendezvous, and interplanetary travel.

Use cases

• simulate realistic orbital mechanics and spaceflight
• practice rendezvous and docking with a space station
• plan and fly interplanetary missions
• learn how real ascent-to-orbit works
• fly historic or fictional spacecraft in the solar system
• develop custom spacecraft or graphics addons

When to choose

• you want a realistic, physics-based spaceflight sandbox rather than an arcade game
• you want to learn orbital mechanics hands-on
• you want an extensible, open-source simulator you can modify or build addons for

When to avoid

• you want predefined missions, combat, or trading gameplay
• you need a cross-platform simulator (it is Windows-only and 32-bit)
• you prefer casual, easy-to-pick-up space games
