In July 2012, a rotational lightcurve of "Tycho Brahe" was obtained by Renata Violante and Martha Leake, that gave a short rotation period of 3.89 hours with a brightness variation of 0.38 magnitude (). According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Tycho Brahe" measures 11.78 kilometers in diameter, and its surface has an albedo of 0.221 (revised 2014-figures).
