Here we present the results of visible range light curve observations of ten Centaurs using the Kepler Space Telescope in the framework of the K2 mission .
Well defined periodic light curves are obtained in six cases allowing us to derive rotational periods , a notable increase in the number of Centaurs with known rotational properties .

The low amplitude light curves of ( 471931 ) 2013 PH _ { 44 } and ( 250112 ) 2002 KY _ { 14 } can be explained either by albedo variegations , binarity or elongated shape .
( 353222 ) 2009 YD _ { 7 } and ( 514312 ) 2016 AE _ { 193 } could be rotating elongated objects , while 2017 CX _ { 33 } and 2012 VU _ { 85 } are the most promising binary candidates due to their slow rotations and higher light curve amplitudes .
( 463368 ) 2012 VU _ { 85 } has the longest rotation period , P = 56.2 h observed among Centaurs .
The P > 20 h rotation periods obtained for the two potential binaries underlines the importance of long , uninterrupted time series photometry of solar system targets that can suitably be performed only from spacecraft , like the Kepler in the K2 mission , and the currently running TESS mission .
