The muon is named after the Greek letter mu, which is the first letter of the Greek word for magnet. The muon is a subatomic particle that is similar to the electron, but has a much larger mass. The muon is a lepton, which means it has no charge. The muon is also a meson, which means it is a particle that is made up of two quarks.
