Real-time universe simulator 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. EULA(End User License Agreement): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

🌏 Amazing astronomy app! 🔭

Celestia is a wonderful app that makes not just the solar system, but practically the whole galaxy (and more) accessible to your fingertips, which makes it so entertaining and educational. Planets, stars, galaxies, satellites, our solar system are just some things you can find in the app, in 3D.One feature about the app are ‘add-ons’ and they (of course) add more content to the application, though I advise not getting a lot of them, some of them are heavy and can increase the size of the program. But I seriously recommend getting this app if you love space, and more! 🌌

I was an avid user of Celestia on the computer when I was a kid. I’d come home and explore the Galaxy for what seemed like hours. When I heard they were continuing development, including making a mobile app, I was beyond excited. I downloaded it, played around with it on the phone, and enjoyed myself. It was a great throwback, but there is just something different about it, since it is adapted for a smaller touch screen device. First, it has the same old feel, but it seems less than the computer version. I know as a kid I installed massive amounts of add-ons to make it even more enjoyable, but I found the vanilla version on my phone to be bland. The quality seems to not be scaled down for the phone’s ppi ratio. All of these things I noticed are probably going to be fixed, along with hopefully some updated textures, such as Pluto’s newly revealed surface. Thank you for a life long dream of mine, keep improving, I am genuinely impressed so far. The program that once took a large computer to run only needs a phone’s computer chip now.

I have been wishing and hoping for a mobile version of Space Engine, and it’s finally being done! I am absolutely blown away by how much you can do with Celestia! It has some bugs. Like, when I visit a galaxy and all I see is a flat white circle or square. Or, when I downloaded the Star Wars Galaxy, but it is so glitchy that you really can’t see a damned thing. This game also needs a spacecraft option, so I can fly around and manually land on planets and moons. Anyway, this is probably the BEST space app I have ever seen!

1. Data update (2025-12-16) 2. Try lookup with component A suffix after trying catalog lookup 3. Add an Update button for add-ons that have updates available (only supported for newly installed add-ons from this version or later)
