Abstract
Since the first planetary object was detected outside of the solar system, in 1991, over 100 extra-solar planets have been catalogued. This article describes how they are detected, what we know about them so far and includes a full listing of all known exoplanets. The science is in its infancy, and by the time school students graduate from university we expect to have developed the technology to understand whole systems of planets containing some that match our own.
