Definition
An exomoon is a natural satellite (as opposed to an artificial satellite) of an extrasolar planet. In analogy to the solar system where many of the planets have moons around them, it is expected that extrasolar planets will host moons as well. No exomoon has yet been discovered (as of 2014), as the detection of exomoons is a very complicated task with all current detection techniques.
