880 Herba is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on 22 July 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]
880 Herba is named after Herba, the Greek god of misery and poverty.[3]
