Bortset fra Solen er de st\u00f8rste himmellegemer i Solsystemet de otte store planeter. T\u00e6ttest p\u00e5 Solen ligger fire forholdsvis sm\u00e5, stenplaneter \u2013 Merkur, Venus, Jorden og Mars.<\/p>\n<\/div>\n<p>Uden for Mars ligger asteroideb\u00e6ltet \u2013 et omr\u00e5de, der rummer millioner af stenagtige legemer. Disse er rester fra planeternes dannelse for 4,5 milliarder \u00e5r siden.<\/p>\n<p>P\u00e5 den anden side af asteroideb\u00e6ltet ligger de fire gasplaneter \u2013 Jupiter, Saturn, Uranus og Neptun. Disse planeter er meget st\u00f8rre end Jorden, men meget lette i forhold til deres st\u00f8rrelse. De best\u00e5r hovedsageligt af brint og helium.<\/p>\n<p>Indtil for nylig var den fjerneste kendte planet en iskold verden ved navn Pluto. Pluto er dog langt mindre end Jordens m\u00e5ne, og mange astronomer mener, at den er for lille til at kunne kaldes en rigtig planet.<\/p>\n<p>I 2005 blev der opdaget et objekt ved navn Eris, som er mindst lige s\u00e5 stort som Pluto, meget langt fra Solen. I de senere \u00e5r er der blevet opdaget mere end 1.000 isverdener som Eris uden for Plutos bane. Disse kaldes Kuiperb\u00e6lteobjekter. I 2006 besluttede Den Internationale Astronomiske Union, at Pluto og Eris skal klassificeres som \u201cdv\u00e6rgplaneter\u201d.<\/p>\n<p>Endnu l\u00e6ngere ude befinder Oort-skyens kometer sig. De er s\u00e5 langt v\u00e6k, at de ikke kan ses, selv ikke med de st\u00f8rste teleskoper. Indimellem forstyrres en af disse kometer og bev\u00e6ger sig mod Solen. Den bliver da synlig p\u00e5 nattehimlen.<\/p>","protected":false},"excerpt":{"rendered":"<p>The Solar System is made up of the Sun and all of the smaller objects that move around it.
