    A comet is named after its first independent discoverers, up to a maximum of three names, separated by hyphens. [ 30 ] [ 31 ] The IAU prefers to credit at most two discoverers, and it credits more than three discoverers only when "in rare cases where named lost comets are identified with a rediscovery that has already received a new name."
