Pogosto jih imenujemo \u2018manj\u0161i planeti\u2019.<\/p>\n<\/div>\n<p>Domneva se, da obstajajo milijarde teh skalnih kosov. Ve\u010dina jih le\u017ei v \u2018glavnem pasu\u2019 v obliki krofa med tirnicama Marsa in Jupitra. Na notranjem robu tega glavnega pasu asteroidi za en obhod okoli Sonca potrebujejo pribli\u017eno tri leta. Tistim, ki se nahajajo blizu zunanje meje glavnega pasu, to traja dvakrat dlje.<\/p>\n<p>Beseda \u2018asteroid\u2019 pomeni \u2018zvezdni\u2019. To ime so dobili, ker jih je v ve\u010dini teleskopov mogo\u010de videti le kot svetlobne to\u010dke. V za\u010detku 20. stoletja so jih astronomi imenovali \u2018nebe\u0161ki \u0161kodljivci\u2019. Bili so vidni v tako velikem \u0161tevilu, da so pokvarili fotografije oddaljenih galaksij in meglic.<\/p>\n<p>Najve\u010dji med asteroidi, Ceres, je bil odkrit kot prvi. Odkril ga je Giuseppi Piazzi iz Palerma na Siciliji 1. januarja 1801.<\/p>\n<p>Drugi manj\u0161i planet \u2013 Pallas \u2013 je leta 1802 odkril Wilhelm Olbers. Sledila sta mu Juno (1804) in Vesta (1807). Od leta 1847 ni minilo niti eno leto, v katerem ne bi odkrili vsaj enega asteroida.<\/p>\n<nav class=\"related\" aria-label=\"Povezano\">\n<h2 class=\"related__heading\">Povezano<\/h2>\n<div class=\"grid related__grid\">\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/sl\/asteroider_de_smaa_planeter\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">danski<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/sl\/planetoiden_-_de_kleine_planeten\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">nizozem\u0161\u010dina<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/sl\/asteroiden_-_die_kleinplaneten\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">nem\u0161\u010dina<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/sl\/asteroider_de_smaa_planetene\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">norve\u0161ki<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/sl\/asteroidy_czyli_planetoidy\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">polj\u0161\u010dina<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/sl\/asteroider_smaaplaneterna\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">\u0160ved\u0161\u010dina<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<\/div>\n<\/nav>","protected":false},"excerpt":{"rendered":"<p>Asteroids are small, rocky bodies that have been left over from the formation of the planets 4.5 billion years ago.
