Opsomming

Beskrywing

English: Proteus is the second largest moon of Neptune behind the mysterious Triton. Proteus was discovered only in 1989 by the Voyager 2 spacecraft. This is unusual since Neptune has a smaller moon - Nereid - which was discovered 33 years earlier from Earth. The reason Proteus was not discovered sooner is that its surface is very dark and it orbits much closer to Neptune. Proteus has an odd box-like shape and were it even slightly more massive, its own gravity would cause it to reform itself into a sphere.

Deutsch: Proteus ist hinter dem geheimnisvollen Triton der zweitgrößte Mond des Neptuns. Proteus wurde erst 1989 durch das Voyager 2 Raumschiff entdeckt. Das ist ungewöhnlich, da Neptun einen kleineren Mond - Nereid - hat, der schon 33 Jahre früher von der Erde aus entdeckt wurde. Der Grund für Proteus' späte Entdeckung war seine sehr dunkle Oberfläche. Auch seine Umlaufbahn ist viel näher bei Neptun als die von Nereid. Proteus hat eine ungewöhnliche kastenartige Form und wäre er nur wenig masserreicher, würde ihn seine eigene Schwerkraft in eine Kugel umformen.
