Celestia - Space Simulator for iPhone

Product summary

Celestia is a real-time, three-dimensional space simulator that lets you travel through the cosmos. Its extensive object database lets you visit planets, moons, star clusters and distant galaxies while observing them from any vantage point and moment in time. The engine computes positions and motions of solar-system bodies continuously and can run at faster or slower speeds according to your preference.

Navigation and viewing tools

• Precision tracking of planetary and satellite motion, updated in real time and adjustable to any time scale.
• Immersive point-of-view travel that lets you jump to objects and even touch down on surfaces for close-up inspection.
• Quick keyboard shortcuts to show or hide labels and overlays, plus smooth zooming to examine features (for example, the Galilean moons around Jupiter).

Expandability and user content

• 3D models and trajectory data for asteroids, spacecraft and other moving objects, letting you add accurately modeled visitors to the simulation.
• High-resolution planetary textures (such as detailed Earth maps) to improve visual fidelity for well-mapped bodies.
• Fictional and fan-created entries from popular sci-fi universes for users who want imaginative extras.
• Additional catalog entries like newly discovered comets and stars to grow the available object set.

Who benefits from it

Celestia is well suited for students, hobbyist astronomers and anyone curious about space. Its realistic orbital mechanics and flexible presentation make it useful as a teaching aid as well as an engaging tool for casual exploration.
