Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico, in 2011 gave a light curve with a period of 12.266 ± 0.001 hours and a brightness variation of 0.13 ± 0.02 in magnitude. The curve is asymmetrical with one maxima and one minima.[2]
880 Herba is named after Herba, the Greek god of misery and poverty.[3]
