Pluto blev opdaget i 1930 af den 24-\u00e5rige Clyde Tombaugh, der brugte et specielt apparat til at sammenligne billeder af himlen. Det viste sig at v\u00e6re en lille verden, endda mindre end vores M\u00e5ne.<\/p>\n<\/div>\n

Pluto bev\u00e6ger sig i en elliptisk (\u00e6gformet) bane, der varierer mellem 7.381 millioner km (49 gange afstanden mellem Solen og Jorden) og 4.446 millioner km (30 gange afstanden mellem Solen og Jorden). Da en oml\u00f8bsperiode varer 248 \u00e5r, ville ingen, der blev f\u00f8dt p\u00e5 Pluto, nogensinde opleve en eneste f\u00f8dselsdag!<\/p>\n

Der vides meget lidt om Pluto. Dens overflade er ekstremt kold (-230 grader C) og synes at v\u00e6re d\u00e6kket af frosset is. I de seneste \u00e5r har den befundet sig ret t\u00e6t p\u00e5 Solen og har nydt en kort sommer. Islaget p\u00e5 overfladen er fordampet og har dannet en tynd atmosf\u00e6re. Nu tr\u00e6kker den sig imidlertid tilbage i solsystemets kolde dybder, og denne atmosf\u00e6re vil snart fryse til igen.<\/p>\n

Pluto roterer \u201cbagl\u00e6ns\u201d (fra \u00f8st mod vest) \u00e9n gang hver 6. dag og 9 timer. Dens st\u00f8rste m\u00e5ne, Charon, bruger lige s\u00e5 lang tid p\u00e5 at kredse om Pluto. Det betyder, at man aldrig ville kunne se Charon, hvis man boede p\u00e5 den ene side af Pluto. For nylig er der blevet opdaget to mindre m\u00e5ner med Hubble-rumteleskopet.<\/p>\n

I mange \u00e5r blev Pluto betragtet som den niende planet regnet fra Solen (selvom den nogle gange kommer t\u00e6ttere p\u00e5 Solen end Neptun). I dag betragtes den som en \u201cdv\u00e6rgplanet\u201d. Den er ogs\u00e5 et af de st\u00f8rste legemer i Kuiperb\u00e6ltet, en gruppe af isverdener, der befinder sig i rummet uden for Neptuns bane.<\/p>","protected":false},"excerpt":{"rendered":"
