Frequently Asked Questions


What is a mobile / inflatable planetarium?

A planetarium is a theatre that is designed to entertain and educate visitors about astronomy and the night sky. Most planetariums are dome-shaped with images and videos projected onto the dome so that they can be made to appear and move realistically to simulate their motion.

An inflatable or mobile planetarium replicates this idea but with the difference that it can be easily transported to places where people already are, a typical example being a school or community space.


How does an inflatable planetarium work?

The dome is transported in a large bag and then rolled out in your school hall. It is inflated by a large fan. The air pressure inside holds its shape and gravity (its weight) holds it down! The inside of the dome is made from a material which is designed to be projected on and when you are in total darkness of the planetarium you really feel you are in space.


Can these domes be used outdoors?

All our domes are made for indoor use only; due to their lightweight nature and the fact they are not attached to the floor they could easily blow away with the wind. They can be used outside if sheltered inside a dry, secure marquee with the sides down.


How long can I book the mobile planetarium for?

You can book us for a full day (4 – 8 shows).

Unloading and set up of the planetarium takes approximately 60 minutes, with similar time required for pack down and loading. There should not be any other activity in the venue space during set up / pack down.

Each presentation lasts approx. 30 – 45 minutes, depending on your schedule. We will communicate with you in advance to arrange the length and types of the show. The whole experience will include pre-presentation points, entry / exit, and questions.


Do you offer accessible shows?

All our domes are fully wheelchair accessible. Please note however, that whilst our domes are wheelchair accessible, there is limited space in the planetarium. Please see the section 'how many people the domes can accommodate' below for further details.

We aim to make our digital dome experiences as accessible as possible. However, you must let UK Astronomy know in advance if any of the participants have additional needs or require reasonable adjustments. We will do everything we can to accommodate your needs.


How big are the planetarium domes?

We operate two domes. The smallest has a diameter of 5 meters and the largest has a diameter of 6 meters.


How many people can the domes accommodate?

The 5 meter dome can accommodate up to 30 small children (+2 teachers) or 10 - 15 secondary school students (+1 teacher) or 10 - 15 adults or up to 20 mixed, with a very limited wheelchair capacity.

The 6 meter dome can accommodate up to 55 small children (+3 teachers) or 35 - 40 secondary school students (+3 teachers) or 35 - 40 adults or 35 mixed or 8 small wheelchair users or 4 large wheelchair users.

Please note that these are the capacities for audience seated on the floor to achieve max capacity. If chairs are required or audiences are lying down, then capacity is greatly reduced.


How much space do the domes require?

The 5 meter dome requires 6 x 6 meters floor space with a 3 meter high ceiling. The 6 meter dome requires 7 x 7 meters floor space with a 4 meter high ceiling.


How long does it take to set up and take down?

It takes approximately 60 minutes to set up and similar amount of time to take down.


Who are inflatable planetariums for?

They are very popular with schools, youth groups or other groups.


Why are planetariums good for schools?

Mobile planetariums are popular for several reasons:

No Missed Lessons - all other regular classes can be attended as normal.

No Missed Lunches - free meals can be taken at school as normal.

No Stress - pupils remain within the safe and familiar school environment.

No Paperwork - for busy teachers to complete.

Better Quality Teaching - being smaller than fixed planetariums, portable domes are more intimate and in the hands of our skilled volunteers they result in more effective learning / pupil engagement.


Do you provide a risk assessment?

Yes, please feel free to download our Planetarium Risk Assessment.
