Be transported to distant galaxies at London's only 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.

Take a stunning tour of the universe from the comfort of your seat or get a preview of> what you can see in tonight's sky. You'll even get to meet a real astronomer!

Combining real images from spacecraft and telescopes with advanced CGI, all projected onto a fully immersive dome, a visit to the Peter Harrison 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.

There are shows packed with awe and wonder to suit everyone from curious under 7s to space obsessed adults and the Planetarium can also be booked for schools groups. 

Arrive early

The Planetarium is at the top of a steep hill in Greenwich Park. Walking time from Greenwich Station / Cutty Sark DLR is about 25 mins, or 20 mins from National Maritime Museum. Please leave enough time as unfortunately latecomers cannot be admitted. Aim to arrive at least 10 mins before the show’s starting time.

Amazing architecture

It’s not just the shows that are breath taking. The Planetarium has won awards for its design, which features a bronze cone made from nearly 250 pieces, welded together and patinated to look like a single piece. It is one of single largest uses of bronze in the world.

Love under the stars

Star-crossed lovers can even hire the Planetarium for marriage proposals.
