Dans le cadre de sa mission passionnante, Cheops mesurera avec pr\u00e9cision les dimensions de petites exoplan\u00e8tes \u2013 dont la taille varie de celle de la Terre \u00e0 celle de Neptune \u2013 dont nous connaissons d\u00e9j\u00e0 la masse, afin de d\u00e9terminer leur densit\u00e9. Il observera \u00e9galement des \u00abJupiters chauds\u00bb en orbite proche de leur \u00e9toile m\u00e8re afin d\u2019en savoir plus sur leur atmosph\u00e8re et d\u2019identifier des cibles int\u00e9ressantes pour des observations approfondies par de futures missions. Cheops est le fruit d\u2019un partenariat entre l\u2019ESA et la Suisse, avec un consortium d\u00e9di\u00e9 dirig\u00e9 par l\u2019Universit\u00e9 de Berne, et b\u00e9n\u00e9ficie de contributions importantes de l\u2019Autriche, de la Belgique, de la France, de l\u2019Allemagne, de la Hongrie, de l\u2019Italie, du Portugal, de l\u2019Espagne, de la Su\u00e8de et du Royaume-Uni.<\/p>\n<p>Cheops a \u00e9t\u00e9 lanc\u00e9 le 17 d\u00e9cembre depuis le port spatial europ\u00e9en de Kourou, en Guyane fran\u00e7aise. <\/p>\n<p>Cr\u00e9dit : Consortium Cheops<\/p>","protected":false},"excerpt":{"rendered":"<p>Find out how Cheops, the Characterising Exoplanet Satellite, is going to investigate distant planets orbiting stars other than the Sun to discover what these alien worlds are made of.
