The Hong Kong Space Museum's planetarium also had all of its seats replaced by a French company. The new seats, which are equipped with an interactive system that supports multiple languages, can be reclined for a better viewing angle inside the projection dome. Also, the audience can view not only the night sky as simulated from the surface of the earth, but also that as simulated from the surface of the other planets in the solar system. In the night sky, the shapes of different constellations can be seen, and the changes in polar nights from outer space can also be tracked.
