Stan Gibilisco: Comets, meteors & asteroids–how they affect earth. 1. Auflage. Tab Books, Blue Ridge Summit, PA 1985, ISBN 0-8306-1905-4, S.76 (englisch, eingeschränkte Vorschau in der Google-Buchsuche): “What if two or more different people discover the same Komet at about the same time? This problem is solved by allowing a comet to bear as many as three names. The names are separated by hyphens. Thus we have had comets such as Ikeya-Seki and Arend-Roland. It has been decided that more than three names would be ridiculous und cumbersome. Therefore, we do not hear of comets such as Jones-Smith-James-Olson-Walters-Peterson-Garcia-Welch!”
