COROT ble f\u00f8rt inn i bane av en ny versjon av Soyuz-raketten og ble skutt opp fra Baikonur-kosmodromen i Kasakhstan kl. 15.23 CET. 50 minutter senere ble den 630 kg tunge satellitten plassert i en perfekt pol\u00e6r bane, 900 km over jorden.<\/p>\n<\/div>\n<p>Siden den gang har COROTs 30 cm-teleskop og sv\u00e6rt f\u00f8lsomme kamera blitt brukt til \u00e5 studere \u2018stjernejordskjelv\u2019 og lete etter nye verdener. Romfart\u00f8yet gj\u00f8r dette ved \u00e5 fange opp det svake lyset fra 120 000 stjerner og sende det videre til et spesielt kamera best\u00e5ende av to deler.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"537\" data-credit=\"CNES\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2006\/11\/Planet_transit_in_front_of_a_star2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2006\/11\/planet_transit_in_front_of_a_star2\/17867526-3-eng-GB\/Planet_transit_in_front_of_a_star.jpg\" alt=\"Planet transit in front of a star\"><figcaption>Planet som passerer foran en stjerne<\/figcaption><\/figure>\n<p>Den ene halvdelen av kameraet er utformet for \u00e5 oppdage fjerne planeter. Dette gj\u00f8res ved \u00e5 registrere svake fall i en stjernes lysstyrke n\u00e5r en planet beveger seg foran den. Mange av objektene COROT har funnet, er \u2018varme Jupiter-planeter\u2019 \u2013 gigantiske planeter som ligger sv\u00e6rt n\u00e6r stjernene sine. Imidlertid har det ogs\u00e5 oppdaget et lite antall \u2018superjordene\u2019. Disse steinplanetene er bare noen f\u00e5 ganger st\u00f8rre enn Jorden. COROT-7b \u2013 med en diameter p\u00e5 mindre enn det dobbelte av Jordens \u2013 var den minste eksoplaneten som noensinne er funnet.<\/p>\n<p>Den andre halvdelen av kameraet kan registrere sv\u00e6rt sm\u00e5 endringer i lysutstr\u00e5lingen fra en stjerne, for\u00e5rsaket av lydb\u00f8lger som beveger seg over overflaten. Disse ligner jordskjelvb\u00f8lger p\u00e5 Jorden, og gj\u00f8r det mulig for forskere \u00e5 l\u00e6re mye om forholdene inne i hver enkelt stjerne.
