    574 Reginhild is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on September 19, 1905.

    Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico during 2010 gave a light curve with a period of 14.339 ± 0.001 hours and a brightness variation of 0.17 ± 0.02 in magnitude. The light curve shows three uneven minimums and maximums per rotation cycle.[2]
