    563 Suleika is a minor planet orbiting the Sun. Previously designated as 1905 QK, it was discovered by German astronomer Paul Götz on April 6, 1905 from Heidelberg, Germany.[3]

    Photometric observations of this asteroid at the Oakley Observatory in Terre Haute, Indiana during 2006 gave a light curve with a period of 5.628 ± 0.002 hours and a brightness variation of 0.28 ± 0.01 in magnitude.[4]
