There were some 3000 binaries discovered in the Kepler main mission, and there is a growing collection of binaries that have been found to date in the 2-wheel extension of the Kepler mission, called ‘K2’. Among this impressive collection of mostly eclipsing binaries, some 220 triple stars have been detected, mostly through eclipse timing variations, but some via 3rd-body eclipses. In addition to the large sample of triple-star systems, a number of higher-order multiple star systems have also been discovered using Kepler data plus follow-up ground-based observations, like the quadruple systems KIC 4247791 (Lehmann et al. 2012) and KIC 7177553 (Lehmann et al. 2016), or the quintuple system KIC 4150611 (Shibahashi & Kurtz 2012, Prsa et al. 2016). We report on the first quintuple star system found in the K2 fields, and one of the few that contain two eclipsing and spectroscopic binaries.
