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.

good graphics, meh navigation. anytime you try to zoom in or out, it thinks you're selecting something in the background and a menu pops up for it. pinch zooming is impossible for this reason. if a body, like Saturn, has a lot of satellites you'll waste your time selecting all the dozens of moons and never be able to actually select Saturn. I have to search it even when I can see it labelled, otherwise waste time clicking on moons I can't even see.

It is amazing, probably the best space explorer game on mobile, the amount of objects are amazing, almost anything I can think of is in this game, and if it isnt its probably installable as an addon. There is only one big problem on mobile that stops me from rating it 5 stars, and that is that the controls are very janky and weird on mobile. If the controls were fixed and maybe some background music was added this would definitively be the best mobile space explorer game.
