Comet van Gent–Peltier–Daimaca, formally designated as C/1943 W1, is a non-periodic comet with a rather peculiar discovery. It was independently discovered by four astronomers, however the established system of naming comets by the International Astronomical Union only recognizes the names of the first three people who observed it.
