Kepler-68 is a Sun-like main sequence star located away in the constellation Cygnus. It is known to have at least four planets orbiting around it. The third planet has a mass similar to Jupiter but orbits within the habitable zone.

High resolution imaging observations of Kepler-68 carried out with the lucky imaging instrument AstraLux on the 2.2m telescope at Calar Alto Observatory detected a wide companion candidate approximately 11 arcseconds away. Comparing these observations to the 2MASS positions showed that the companion's proper motion appeared consistent with it being bound to the Kepler-68 system, but further observations were needed to confirm this conclusion. In 2019 this was found to be an unrelated background star using Gaia DR2 astrometry.
