Summary, in English

As we look up at night we see that our Earth has one moon orbiting it, the one we call the Moon. We have explored our moon with orbiters, rovers and astronauts, mapping it and studying its history.
Other planets also have moons in orbit around them and these may look quite different from the Earth's moon. Some are small and look like asteroids, others are so icy they would become comets if they plunged on an elliptical orbit towards the inner solar system.

This full dome planetarium production; "What makes a moon?, we travel round the Solar System trying to identify what is needed to classify an object as a moon.
