Discover the moons of the Solar System in this brand new show narrated by our Royal Observatory astronomers.

From the Earth’s closest neighbour in space, our Moon, to the moons of the distant gas giants, this show explores our Solar System’s natural satellites.

Voiced by our Royal Observatory astronomers, discover more about the appearance and features of our own moon, as well as a selection of the many different kinds of moons out there that orbit the other planets.

Planetarium shows last up to 30 minutes.

Age: 7+

Children under 13 must be accompanied by an adult.

Arriving at the Planetarium

The Planetarium is part of the Royal Observatory, located on a hill with spectacular views across London. Please allow enough time to get to us and aim to arrive at least 10 mins before a show’s start time, as latecomers cannot be admitted.

Please note that pushchairs are not allowed into the planetarium itself but there is a designated buggy park in the foyer. 

The Planetarium is open daily, except for the first Wednesday of every month when it is closed for essential maintenance.
