An Orrery is a moving, mechanical model that shows how the planets orbit around the Sun within the Solar System.

This Electric Orrery is a virtual orrery that will let you see where the planets are today, where they were in the past, and where they will be in the future.

Note that the Electric Orrery is written in a computer language called Java, so may not work if your internet browser is not set up to run Java programmes.
