It was discovered by the Small Sky Survey of the [[Kepler (spacecraft)|Kepler space telescope]]. All six planets transit the star's disk as viewed from the Earth's perspective. This allows, via monitoring of the eclipsing of the star by the planets, direct measurements of the planets' periods and diameters. Kepler-11 is the first discovered exoplanetary system with more than three planets [[Methods_of_detecting_extrasolar_planets#Transit_method|transiting]] and is also the most compact known system.<ref>[http://www.nasa.gov/mission_pages/kepler/news/new_planetary_system.html Nasa Report]</ref> The planets are named alphabetically, starting with the innermost: ''b'', ''c'', ''d'', ''e'', ''f'', and ''g''.
 
Kepler-11 je zvezda podobna Soncu, za kateri so potrdili, da ima najmanj šest ekso-planetov z kratko-periodičnimi orbitami. Planetarni sistem je bil odkrit 2. februarja 2011. Ta se nahaja v smeri ozvezdja Labod; zvezda je oddaljena okoli 2000 svetlobnih let. Odkrili so ga z majhnim preiskovanjem neba (Small Sky Survey) s teleskopom Kepler. Vseh šest planetov prehaja disk zvezde, gledano iz vidika Zemlje. To omogoča, preko spremljajo zatemnitev zvezde s planeti, neposredne meritve periode planetov, njihove mase in premerov; sledi tudi gostota teh svetov. Kepler-11 je prvi odkril izven-sončni sistem z več kot tremi planeti v tranzitu. To je tudi najbolj znan stisnjen sistem. Planeti so poimenovali po abecedi, začenši z najmanjšim: b, c, d, e, f in g.
