[1] The stony S-type asteroid has a notably short rotation period of 3.0 hours and measures approximately 15 kilometers (9.3 miles) in diameter.
[2] Mitaka is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
Nowadays the city of Mitaka hosts the headquarters of the National Astronomical Observatory of Japan with the Tokyo Photoelectric Meridian Circle, public relation and data centers, and several telescopes.
[12][13][16][17] Analysis of the best rated lightcurve by French amateur astronomer Pierre Antonini gave a rotation period of 3.0361 hours with a consolidated brightness variation of 0.23 to 0.62 magnitude (U=3).
[6][7][8][9][10] The Collaborative Asteroid Lightcurve Link adopts Petr Pravec's revised WISE results with an albedo of 0.1549 and takes a diameter of 16.02 kilometers based on an absolute magnitude of 11.62.
