Glossarbegriffe: Kuipergürtel

Description: Der Kuipergürtel ist eine ringförmige Region, die größtenteils jenseits der Umlaufbahn des Neptun liegt. Sie enthält vor allem kleine, eisige Objekte. Die meisten Objekte befinden sich einer Entfernung von 40-48 Astronomischen Einheiten von der Sonne.

Die Objekte im Kuipergürtel sind meistens klein, obwohl sich dort auch mehrere Zwergplaneten wie Pluto befinden. Im Gegensatz zu den kleinen Himmelskörpern und Zwergplaneten im Asteroidengürtel bestehen die Objekte im Kuipergürtel hauptsächlich aus gefrorenem Wasser, Methan und Ammoniak.

Image of Pluto in enhanced colour to bring out differences in surface composition. They include craters, ridges and plains.


Bildunterschriften: NASA's New Horizons spacecraft captured this high-resolution enhanced colour view of the dwarf planet Pluto on in July 2015. The image combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC). Pluto’s surface appears enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. The image resolves details and colours on scales as small as 1.3 kilometers.
