[1] The dark carbonaceous C-type asteroid has a rotation period of 14.1 hours and measures approximately 76 kilometers (47 miles) in diameter.
[2] Leopoldina is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[2] In April 2008, a rotational lightcurve of Leopoldina was obtained from photometric observations by Brian Warner at the Palmer Divide Observatory (716) in Colorado.
Analysis gave a classically shaped bimodal lightcurve with a well-defined rotation period of 14.115±0.003 hours and a brightness variation of 0.18±0.02 magnitude (U=3).
[6][7][8] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0497 and a diameter of 76.14 kilometers based on an absolute magnitude of 9.47.
