“4962 Vecherka”的意思、由来-开放百科全书

It orbits the Sun in the central main-belt at a distance of 2.2–3.0 AU once every 4 years and 3 months (1,537 days). Its orbit has an eccentricity of 0.15 and an inclination of 15° with respect to the ecliptic. The body's observation arc begins with its first observation as {{mp|1952 TF}} at Uccle Observatory in October 1952, or 21 years prior to its official discovery observation at Nauchnij.^[24]

Physical characteristics

Slow rotator

In August 2015, a rotational lightcurve of Vecherka was obtained from photometric observations by a collaboration of Bulgarian astronomers. Lightcurve analysis gave a long rotation period of {{val|336|48}} hours with a brightness variation of 1.08 magnitude ({{small|U=2}}), indicating that the body's shape is irregular and elongated rather than spherical.^[11] This long period makes Vecherka a slow rotator, which ranks among the Top 200 slowest ones known to exists.

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Vecherka measures between 8.54 and 9.951 kilometers in diameter and its surface has an albedo between 0.210 and 0.349.^[6]^[7]^[8]^[9]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 10.06 kilometers based on an absolute magnitude of 12.3.^[3]

Naming

Based on a proposal by the Institute of Theoretical Astronomy (ITA), this minor planet was named after Vechernij Petersburg, a popular evening newspaper from Saint Petersburg, Russia, that publishes astronomical information and articles popularizing astronomical knowledge on a regular basis.^[2] The official naming citation was published by the Minor Planet Center on 14 December 1997 ({{small|M.P.C. 31023}}).^[38]

It was discovered on 1 October 1973, by Soviet astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula.^[24] The asteroid was named after Vechernij Petersburg, a newspaper that also publishes astronomical information.^[2] Orbit and classification Vecherka is a member of the Eunomia family ({{small\|502}}), a prominent family of stony S-type asteroid and the largest one in the intermediate main belt with more than 5,000 members.^[3] However, Vecherka turns out to be a non-family asteroid from the main belt's background population when applying the Hierarchical Clustering Method to its proper orbital elements.^[4] It orbits the Sun in the central main-belt at a distance of 2.2–3.0 AU once every 4 years and 3 months (1,537 days). Its orbit has an eccentricity of 0.15 and an inclination of 15° with respect to the ecliptic. The body's observation arc begins with its first observation as {{mp\|1952 TF}} at Uccle Observatory in October 1952, or 21 years prior to its official discovery observation at Nauchnij.^[24] Physical characteristics Vecherka is an assumed stony S-type asteroid, which corresponds to the overall spectral type of the Eunomia family.^[3] Slow rotator In August 2015, a rotational lightcurve of Vecherka was obtained from photometric observations by a collaboration of Bulgarian astronomers. Lightcurve analysis gave a long rotation period of {{val\|336\|48}} hours with a brightness variation of 1.08 magnitude ({{small\|U=2}}), indicating that the body's shape is irregular and elongated rather than spherical.^[11] This long period makes Vecherka a slow rotator, which ranks among the Top 200 slowest ones known to exists.
