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| last=Boyle | first=Alan | authorlink=Alan Boyle | title=Planetary six-pack poses a puzzle | work =MSNBC Cosmic Log | date=2 February 2011 | url=http://cosmiclog.msnbc.msn.com/_news/2011/02/01/5972312-planetary-six-pack-poses-a-puzzle | accessdate=4-02-2011}}</ref><!-- Atmosfer [[hidrogen]] ditemui pada planet ''d'', ''e'' dan mungkin ''f'', sementara ''b'' dan ''c'' mengandung es-es dan/atau H/[[helium|He]].<ref name="Lissauer"/><ref name="Naeye">{{Cite news | last=Naeye | first=Robert | title=Kepler's Outrageous System of Six Planets | work=Sky & Telescope | date=2 February 2011 | url=http://www.skyandtelescope.com/news/115102594.html | accessdate=4 February 2011}}</ref>
