Argon zählt im Universum zu den häufigeren Elementen, in seiner Häufigkeit ist es vergleichbar mit Schwefel und Aluminium. Es ist im Universum nach Helium und Neon das dritthäufigste Edelgas. Dabei besteht das primordiale Argon, das etwa in der Sonne oder Gasplaneten wie Jupiter gefunden wird, hauptsächlich aus den Isotopen Ar und Ar, während das dritte stabile Isotop, Ar, dort nur in geringer Menge vorkommt. Das Verhältnis von Ar zu Ar beträgt etwa 5,7.
