They are thought to have originated deep within 4 Vesta's crust – the family's parent body – possibly from the large Rheasilvia crater on its southern hemisphere near the South pole, formed as a result of a subcatastrophic collision.

[9]: 23 In September 2013, a rotational lightcurve of Palermo was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California.

Lightcurve analysis gave an exceptionally long rotation period of 213.368 hours with a high brightness amplitude of 0.97 magnitude, indicative for an elongated shape (U=2).

The official naming citation was published by the Minor Planet Center on the 200th anniversary of that discovery on 9 January 2001 (M.P.C.
