The Peter Harrison Planetarium is part of the Royal Observatory in Greenwich, with a dome theatre for live, immersive shows about space. Follow an astronomer through the night sky, explore a topic such as the Moon, or choose a family show. The planetarium sits beside the historic observatory in Greenwich Park, so you can plan both into one visit. A planetarium ticket does not include entry to the Royal Observatory itself. Book ahead and arrive at least 15 minutes before your show.
What happens inside the planetarium
Shows use the dome theatre to take you through astronomical subjects, including the night sky and the Moon. In The Sky Tonight, an astronomer explains what you can see in the sky at midnight on the date of the show and points out features to look for. The presentation combines live narration with images across the dome.
Show lengths vary. The Sky Tonight has been presented as a 40-minute programme, while other shows, including one about the Moon, have run for about 30 minutes. Check the programme when choosing a session, especially if you are visiting with children.
Choosing a show for children
The programme includes family sessions, with age-specific options and Ted’s Space Adventures for younger children. The Ted show takes children on a trip through the solar system. Check the current schedule for age guidance and dates before planning your visit.
Planning a visit to Greenwich
The planetarium is at the Royal Observatory in Greenwich Park, close to the observatory’s historic grounds. You can visit both on the same trip, but they have separate admission: a planetarium ticket does not grant entry to the Royal Observatory. The nearby Astronomy Centre is free to visit.
Book your show ahead, particularly around public holidays, when tickets can sell out. Arrive at least 15 minutes before the start, as late entry may be refused. You can take photographs inside before the show begins, but not during the presentation.
