Kepler-7b

Planēta Kepler-7b salīdzinājumā ar Jupiteru.

Kepler-7b ir citplanēta, kas atrodas Liras zvaigznājā. Planēta riņķo ap Kepler-7 zvaigzni 0,06 AU attālumā. 1 gads uz planētas ilgst tikai 4,88 diennaktīs. Planētas masa sastāda 0,433 Jupitera masas, bet tās rādiuss 1,478 reizes lielāks nekā Jupiteram. Aprēķini rāda, ka Kepler-7b vidējais blīvums ir apmēram 0,181 g/cm³, t.i. mazāk par vienu septiņpadsmito daļu no Jupitera blīvuma. Tas nozīmē, ka tā ir viena no "irdenākajām" pašlaik zināmajām planētām. Gāzveida gigants tiek ieskaitīts karsto jupiteru klasē.

Planēta tika atklāta ar teleskopu "Kepler" un par tās atklāšanu astronomu grupa, kas strādā Kepler programmā, paziņoja 2010. gada 4. janvārī. 2013. gadā astronomiem izdevās sastādīt planētas mākoņu segas karti.
