What is a planetarium?
Think of a planetarium as a tour bus of the Universe taking you on amazing journeys to explore and experience the wonders of the night sky. Combining real images from spacecraft and telescopes with advanced CGI, all projected onto a fully immersive dome, the Planetarium can fly you into the heart of the Sun, transport you to distant galaxies, show you the birth of a star or land you on Mars.
The Peter Harrison Planetarium at the Royal Observatory, Greenwich is now London’s only planetarium, and features state-of-the-art HD projection technology, visualisations based on real scientific data and real astronomers.
New shows throughout the day – now better and brighter than ever. Experience a spectacular journey across the Universe at the Peter Harrison Planetarium.
Now London's only planetarium, the Peter Harrison Planetarium is part of the Royal Observatory complex in Greenwich Park and is at the top of a steep hill.
Walking time from Greenwich Station or Cutty Sark DLR is usually approx 25 mins, or 20 mins from the National Maritime Museum. Pay & display parking is available on Blackheath Avenue. Please leave enough time as unfortunately latecomers cannot be admitted.
Access to the Planetarium is through the Astronomy Centre in the Royal Observatory South Building – see floor plans.
The Planetarium is fitted with an induction loop system. Find out more about our Access provision.
