'''Kepler-11''' adalah bintang seperti
Sistem bintang Kepler-11 sangat rapat dan memadati bintang induk. Lima planet tampak seperti mengumpul, sementara satu lainnya seperti "terpental".
== Planet ==
Planet-planet yang mengitari bintang ini dinamai secara alfabetis: ''b'', ''c'', ''d'', ''e'', ''f'', dan ''g''. Ukuran planet-planet tersebut berkisar antara ukuran [[Bumi]] dan [[Neptunus]]. Massa jenis mereka yang rendah menunjukkan bahwa tidak ada satu pun dari planet-planet itu yang komposisinya seperti Bumi.<ref name="Boyle">{{Cite news|
