756 Lilliana is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on April 26, 1908 from Taunton, Massachusetts. It rotates around its axis of rotation every 9.3 hours.
Photometric observations of this asteroid at Palmer Divide Observatory in Colorado Springs, Colorado during 2007 gave a light curve with a period of 9.262 ± 0.001 hours and a brightness variation of 0.83 ± 0.03 in magnitude. A 2012 study based upon observations at the Organ Mesa Observatory in Las Cruces, New Mexico during 2012 produced a conflicting period of 7.834 ± 0.001 hours and a brightness variation of 0.17 ± 0.02 in magnitude. Further study will be needed to resolve the discrepancies in period and amplitude.
