About this app

Celestia — real-time 3D visualization of space

3D Space Simulator | Celestia lets you explore our universe in three dimensions.

Celestia simulates many different types of celestial objects. From planets and moons to star clusters and galaxies, you can visit every object in the expandable database and view it from any point in space and time. The position and movement of solar system objects is calculated accurately in real time at any rate desired.

Interactive Planetarium | Celestia serves as a planetarium – for an observer on any celestial object.

You can easily navigate to any world and land on its surface. When used as a planetarium, Celestia shows accurate positions of solar system objects in the sky. You can switch labels and other supporting features on and off with hotkeys, or zoom in and out on an object of interest, for example Jupiter’s system of moons.

Expandable Content | Customize Celestia according to your needs.

Celestia’s catalogues can be easily expanded. There are many different add-ons available containing new objects like comets or stars, high-resolution textures of Earth and other well mapped solar system bodies, as well as 3D models for asteroids and spacecraft on precise trajectories. Even fictional objects from well-known sci-fi franchises can be found.

I can't begin to tell you how how thrilled I am to find this as an Android app! If I eventually have any bug reports, feature suggestions, or constructive criticism to offer, I'll let you know; but right now this is a solid five stars. One improvement I'd like to see is to make the INFO menu smaller, so it doesn't cover most of the screen; or make its size adjustible.

Nice program that uses a lot of disk space. Too bad there isn't an option to move it to the SDCARD which a lot of programs allow since they are not priority system apps or apps of security. App Info in settings does not give that option to move to sdcard thereby leaving the app stuck on internal memory that is critical to phone operation.

This is the best experience ever. But can you add 4k resolution textures to every surface of a rocky planet. or add hills and mountains and for earth could you add realistic water movement it can be more realistic. And add trees and grass to earth so and also add rain (because rain is cool). And add realistic graphics like bloom, reflections. (sorry if I went to far, I was a bit to excited today.)
