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!

Check out the full list of upcoming planetarium shows and events here.

Frequently asked questions

Where is the Peter Harrison Planetarium?

The Peter Harrison Planetarium is part of Royal Observatory Greenwich, 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.
