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.

Great app, but can be a bit confusing, could use some explaining for certain functions. Also, it says it's real time, but when I view the live feed of the ISS on NASA's official app, the ISS is in a totally different position than it shows in Celestia? Maybe I'm doing something wrong, I dunno. As I said there could be some information about what each function does, it'd be incredibly helpful. If it was a little easier to understand, I'd say it's the best space viewer out there.

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.

A pretty awesome app. A huge range of add ons gives amazing detail on almost any area of astronomy that may interest you - lots of solar system options, also lots of Milky-way details - nebula, SNR, pulsars, black holes, and then lots of galactic options. It's really impressive but does use up a lot of storage. Occasionally a bit buggy - it does crash occasionally but restarts fine.
