About
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.

The OG solar system exploration tool! I put so many hours into this. My greatest accomplishment was flying to Pluto from Earth at sub light speed. It was a very long 16 hours and I really felt just how large the solar system is. Also my computer can finally run this without complaints.
пока мальчики выбирают SpaceEngine, настоящие мужчины покупают Celestia за 80 центов, играют 20 минут и дропают навсегда
First got this in 2003, and it was my first dedicated outlet for worldbuiding my Plutonian Empire universe, though I never really released anything more than Terraformed Pluto and Hadeus, until a few years ago on Celestia Mobile. Glad to see Celestia on Steam. Hopefully our audiences will be a bit bigger now. :)
Прикольная программка, в которой любил позависать в детстве. Пару дней назад я вспомнил как она называется и нашел ее здесь. Сейчас я получил те же ощущения что и в детстве
Glad this is on steam now.
so glad that this is finally on steam. it's not exactly SpaceEngine, but we shouldn't really compare these two, because each serves a different purpose. it's pretty light as well with out-of-the-box workshop support, who would even complain? for anyone wondering, the devs themselves said that this will be free in a short while, so maybe support them before that happens!
DON'S BUY THIS PIECE OF SH*T it's pointless to buy it with there's already universe sandbox and space engine it is super good on mobile but it suck's at PC it's also more harder to go somewhere DON'T BUY IT!!(but if you don't have money you can buy it for a moment and then have something better)
SPACEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
tres bon planétarium , mais un peu difficile a prendre en main
Está realmente chulo. me gustaría que implementaran mejoras gráficas, y en opciones mediciones internacionales por ejemplo grados Celsius. Espero futuras actualizaciones. Lo recomiendo.
