    1069 Planckia is a main belt asteroid. It was discovered by Max Wolf on January 28, 1927 and assigned a provisional designation of 1927 BC. It was named after physicist Max Planck.[1]

    Photometric measurements made in 2000, when combined with earlier observations, showed a light curve with a period of 8.643 ± 0.05 hours.[2] As of 2013, the estimate for the rotation period is 8.665 hours.[3]
