Description
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 would rate this 5, but the reason why I give this a 4-star rating is because your can't change the sky culture of the constellation of stars and that there could be more options so that people can be familiar of what there seeing because I use a star gazing app called tellurium, and I can change the sky culture and there is a lot of options, and I have my culture set to Greek/Latin and I am very familiar with it, and I can't find my favorite stars on celestial because it's not familiar sky culture.

I love this game since I'm a space fan this is like space engine which is nice and add-ons makes it better
★★★★★Franz xian Cabilla· May 8, 2026
Atleast I could see neutron stars black holes nebulas and galaxies
★☆☆☆☆PARTH· Mar 5, 2026
Average app. Not user-friendly. Major issues when using is when trying to zoom in or zoom out while viewing an object of interest it will confuse the pinch in zoom with a hold and open a small menu, every time
★★☆☆☆Petrisor Petrisor· Jun 24, 2026
This game is great it has add-ons, but the controls are not so good Sometime the game controls confuse itself like When I try to zoom out and in while focusing at the planet It opens a small menu And sometimes I cannot zoom out or in even if I did And sometimes its stuck at copying data Rarely for me this game is not for some users I feel like this is the only space explorer game with no ads

Bro I can't search black holes... and unlike space engine just fill it up whatever might be there, why this!
