Zwergstern
Zwergsterne bezieht sich auf mehrere Arten von Sternen. Der Begriff wurde ursprünglich 1906 von dem dänischen Astronomen Ejnar Hertzsprung verwendet. Er bemerkte, dass die rötesten Sterne - im Harvard-Schema als K und M klassifiziert - in zwei verschiedene Gruppen unterteilt werden konnten. Sie sind entweder viel heller als die Sonne oder viel schwächer. Um diese Gruppen zu unterscheiden, nannte er sie "Riesen-" und "Zwergsterne". Die Zwergsterne waren schwächer und die Riesen heller als die Sonne.
Später wurde der Begriff "Zwerg" jedoch erweitert:
