1904 Massevitch, provisionally designated 1972 JM, is a reddish asteroid from the outer region of the asteroid belt, about 18 kilometers in diameter. It was discovered by the Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula, on 9 May 1972.[5]
The surface of the moderately bright R-type asteroid absorbs stronly in the olivine and pyroxene spectral region, which give it its very reddish color. It has an albedo of 0.16 and 0.19, as observed by the Infrared Astronomical Satellite, IRAS and derived by the Collaborative Asteroid Lightcurve Link, respectively.[3] The asteroid orbits the Sun at a distance of 2.5–2.9 AU once every 4 years and 6 months (1,660 days). Its orbit shows an eccentricity of 0.07 and is tilted by 13 degrees to the plane of the ecliptic.[1]
In September 2014, photometric observation of nine asteroids, including 1904 Massevitch, at the Oakley Southern Sky Observatory in Coonabarabran, Australia, determined the asteroid's rotation period to be 5.394±0.003 hours with an amplitude of 0.30 in magnitude.[4]
It is named after Alla Genrichovna Massevitch, a female astronomer-astrophysicist, vice-president of the Astronomical Council of the former USSR Academy of Sciences (now Russian Academy of Sciences), the organizer of optical tracking of artificial Earth satellites in the former USSR.[2]
