    603 Timandra is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on February 16, 1906 in Taunton, Massachusetts.

    Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico during 2010 gave a light curve with a long rotation period of 41.79 ± 0.02 hours and a brightness variation of 0.10 ± 0.02 in magnitude.[2]
