An eon is a made up of two or more eras. They are defined in terms of what was happening on the planet in biological and geological terms rather than in number of years. We are now 541 million yeras (Myr) into the current eon - the Phanerozoic eon. Before that was the Proterozoic eon which lasted 1959 Myr, the Archean eon (1500 Myr) and the oldest, the Hadean eon (500 Myr).
