6537 Adamovich, provisional designation 1979 QK₆, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter.

It was discovered on 19 August 1979, by Soviet–Russian astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula.^[9] The asteroid was later named after Byelorussian writer Aleksandr Adamovich.^[2]

Orbit and classification

Adamovich is a S-type asteroid a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.8–2.6 AU once every 3 years and 3 months (1,175 days). Its orbit has an eccentricity of 0.20 and an inclination of 4° with respect to the ecliptic.^[1]

Physical characteristics

Lightcurve photometry

A fragmentary rotational lightcurve of Adamovich was obtained from photometric observation made at the Palomar Transient Factory in California in February 2013. It showed a provisional rotation period of 2.4±0.1 hours with a brightness amplitude of 0.13 magnitude (U=1).^[7]

Diameter and albedo

According to the surveys carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Adamovich measures 3.22 and 4.3 kilometers in diameter and its surface has an albedo of 0.17 and 0.50, respectively.^[4]^[5]^[6] The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its orbital family – and calculates a diameter of 4.5 kilometers with an absolute magnitude of 13.9.^[3]

Naming

This minor planet was named in memory of Byelorussian–Russian Aleksandr Mikhajlovich Adamovich (1927–1994), publicist, literary scholar and talented writer, known for his civic responsibility.^[2] The official naming citation was published on 4 May 1999 (M.P.C. 34624).^[10]
