Out Of This World: Moons

You've heard plenty about the planets - now let's explore some moons!

We'll begin this morning of science and discovery in our planetarium as we explore the moons of our solar system. Then, join us for an interactive workshop as we put your knowledge to the test! Throughout you'll have the chance to ask our astronomers all the questions you have about space and astronomy.

Recommended for ages 7+.

Please ensure you book the appropriate number of child and adult tickets for your group size. Please note we cannot offer free tickets for under 5s with this event.

Plan your visit

How long will this event last?

The morning will begin with a planetarium show, lasting 30 minutes. Following this, there will be a workshop, lasting up to 45 minutes.

When should I arrive?

The planetarium is part of the Royal Observatory, at the top of a hill with spectacular views across London. Please allow enough time to get to us and aim to arrive at least 15 minutes before the planetarium show’s start time, as latecomers cannot be admitted. Any latecomers will be able to join in with the workshop after the planetarium show though.

What happens if I'm running late?

The planetarium show will begin at the advertised time and late entry to the planetarium will not be possible. However, you will still be welcome to attend the workshop after the show.

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

Are companion/carer tickets available?

Companions to disabled visitors are entitled to free admission. These tickets can be selected online when booking any paid ticket. Please contact the Bookings Team on 0208 312 6608 or email bookings@rmg.co.uk if you have any queries.
