About the Peter Harrison Planetarium
The Royal Observatory is home to London’s only Planetarium.
Lie back in reclining seats and watch as the dome above you fills with stunning simulations of the night sky. Astronomers can show you the sky as it appears on the date you visit, travel deep into the Universe and display amazing astronomy photography and video.
During live shows there’s often a chance to ask questions after the show: don’t miss your chance to speak to a real space expert!

Frequently asked questions
Where is the Peter Harrison Planetarium?
The Peter Harrison Planetarium is part of Royal Observatory Greenwich, a quick, easy journey from central London via train, DLR and bus.
The Planetarium itself is located on the lower floor of the Modern Astronomy Centre (sometimes referred to as the ‘South Building'). If you come to any part of the Royal Observatory site, staff can guide you to the Planetarium.
Please note that the Observatory is at the top of a steep hill within Greenwich Park, around a 15-minute walk from the National Maritime Museum and the Queen’s House. Latecomers cannot be admitted once a show has started, so please check your route beforehand.
When should I arrive?
Please allow enough time to get to us and aim to arrive at least 15 minutes before the show’s start time on your ticket, as latecomers cannot be admitted.
Can children attend?
Yes! This show is suitable for ages 7+. Children under 5 will not be admitted. All children must be accompanied by an adult.
How long do planetarium shows last?
Planetarium shows last up to 30 minutes.
Can I bring a pushchair?
Pushchairs are not allowed into the planetarium itself but there is a designated buggy park in the foyer.
Can I visit the Observatory too?
You do not need a Royal Observatory ticket to visit the Planetarium. However, if you would also like to visit the historic observatory then you can book a separate ticket here.
