EPIC 219217635 was initially identified by K2 as a potential quadruple star system during the spacecraft's Campaign 7, which took place in late 2015. Afterward, a team of astronomers led by Tamas Borkovits of the Baja Astronomical Observatory of Szeged University, Hungary, has conducted follow-up observations of this star, which included radial-velocity spectroscopy, adaptive optics imaging, as well as ground-based photometric observations.

"In this work we report the discovery with NASA's Kepler space telescope during Campaign 7 of its two-wheeled mission (hereafter referred to as 'K2') of a quite likely physically bound quadruple system consisting of two eclipsing binaries," the researchers wrote in the paper.
