[2] Angelica is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[3] Due to this relatively high inclination and eccentricity, Angelica has a Jupiter Tisserand's parameter just barely above 3, which is commonly used as the threshold to distinguish between the populations of asteroids and Jupiter-family comets.
[3][5] During five nights in December 2017, a rotational lightcurve of Angelica was obtained from photometric observations by Tom Polakis at the Command Module Observatory (V02) in Tempe, Arizona.
Lightcurve analysis gave a rotation period of 26.752±0.035 hours with a very low brightness variation of 0.08±0.01 magnitude (U=3−), which is indicative of regular, spherical shape.
[11] Federico Manzini at the Sozzago Astronomical Station (A12) obtained the object's first lightcurve in December 2006, measuring a period of 17.772±0.007 hours and an amplitude 0.06±0.01 magnitude (U=2).
