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''.
