    1910 Mikhailov, provisional designation 1972 TZ1, is a carbonaceous asteroid from the outer regions of the asteroid belt, approximately 35 kilometers in diameter. Discovered at Nauchnyj in 1972, it was named after Russian astronomer Aleksandr Aleksandrovich Mikhailov.

    Discovery

    Mikhailov was discovered on 8 October 1972, by Ukrainian astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[6]

    Zhuravleva is ranked 61 in Harvard's ranking of those who discovered minor planets. Detween 1972 and 1992, She discovered 200 such bodies, 13 of which were co-discoveries.[7]

    Orbit and classification

    The C-type asteroid orbits the Sun in the outer main-belt at a distance of 2.9–3.2 AU once every 5 years and 4 months (1,943 days). Its orbit has an eccentricity of 0.05 and an inclination of 10° with respect to the ecliptic.

    Physical characteristics

    It has a rotation period of 8.88 hours[1] and a low geometric albedo of 0.05.

    Naming

    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]
