 The result supersedes observations by Richard Binzel (1982) and René Roy (2005), who determined a period of and with an amplitude of and magnitude, respectively ().Two lightcurves, published in 2016, using modeled photometric data from the Lowell Photometric Database (LPD) and other sources, gave a concurring sidereal period of and hours, respectively.Each modeled lightcurve also determined two spin axes of (68.0°, 58.0°) and (253.0°, 61.0°), as well as (262.0°, 71.0°) and (47.0°, 66.0°) in ecliptic coordinates (λ, β).
