880 Herba is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on July 22, 1917 in Heidelberg.
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]
