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.

Verdict
The clearest difference is in-app purchases: Multiplanetary Life at none against Celestia's 4. Multiplanetary Life also leads on review sentiment (100% vs 78%). Celestia's advantage is update cadence (every 2 weeks vs every 3 months) and ratings volume (324 vs 3). On price, rating, ads and iOS requirement there is nothing between them.
