11 Cool Solar System/Astronomy apps (Android & iOS)

Over the past decades, humanity has made a huge breakthrough in space exploration.

People find exoplanets. Space missions are carried out. They build large-scale structures to get before inaccessible data. Still, the majority of people have very superficial knowledge about the solar system.

Indeed, many polls show that even adults often have a very vague idea of ​​the movement of objects in space. The reason for this is the lack of visual representation.

The best astronomy apps that are presented in this list will help you fix this problem.
