    1910 Mikhailov, provisional designation 1972 TZ1, is a dark, carbonaceous asteroid in the outer asteroid belt, about 30 kilometers in diameter. It was discovered by Ukrainian astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj on 8 October 1972.[5]

    The C-type asteroid orbits the Sun at a distance of 2.9–3.2 AU once every 5 years and 4 months (1,940 days). It has a rotation period of 8.88 hours[1] and a low geometric albedo of 0.05.

    The asteroid was named in honor of prominent Russian astronomer Aleksandr Aleksandrovich Mikhailov (1888–1983), a gravimetrist and academician, who was vice-president of the International Astronomical Union, director of the Pulkovo Observatory, a member of the Soviet Academy of Sciences and president of its Astronomical Council.[2]

    Zhuravleva is ranked 61 in Harvard's ranking of those who discovered minor planets. She discovered 200 such bodies, 13 of which were co-discoveries, between 1972 and 1992.[6]
