[2][9] The discovery of the asteroid took place during Kowal's follow-up observations of Jupiter's moon Leda, which he had discovered one month prior.
[3] It orbits the Sun in the outer main-belt at a distance of 2.7–3.5 AU once every 5 years and 6 months (2,015 days).
[4][5][6][7] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.072 and a diameter of 29.8 kilometers with an absolute magnitude of 11.1.
[3] A fragmentary rotational lightcurve of Loretta was obtained from photometric observations made by French amateur astronomer Pierre Antonini in March 2011.
It gave an approximate rotation period of 25 hours with a brightness variation of 0.12 magnitude (U=1).
