“1855 Korolev”的意思、由来-开放百科全书

It was first identified as {{mp|1961 JD}} at Goethe Link Observatory in 1961, extending the body's observation arc by 8 years prior to its official discovery observation.^[17]

Orbit and classification

The asteroid orbits the Sun in the inner main-belt at a distance of 2.1–2.4 AU once every 3 years and 4 months (1,231 days). Its orbit has an eccentricity of 0.08 and an inclination of 3° with respect to the ecliptic.

Physical characteristics

Diameter and albedo

According to the surveys carried out by NASA's space-based Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Korolev measures 6.79 kilometers in diameter, and its surface has a high albedo of 0.319,^[5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its orbital family – and calculates a diameter of 7.47 kilometers with an absolute magnitude of 12.8.^[3]

Rotation period

In March 2008, three rotational lightcurves of Korolev were obtained from photometric observation made by astronomers James W. Brinsfield, Petr Pravec and René Roy, giving a well-defined rotation period of 4.65–4.66 hours with a brightness variation 0.75 and 0.76 magnitude, respectively ({{small|U=3/2/3}}).^[7]^[9]{{efn|name=LCDB-Pravec-2008}} Another concurring lightcurve was published in March 2016, using sparse-in-time photometry data from the Lowell Photometric Database ({{small|U=n.a.}}).^[8]

Naming

This minor planet was named in honor of Sergei Korolev (1907–1966), a designer, integrator, organizer and strategic planner. He was the lead Soviet rocket engineer and spacecraft designer in the Space Race between the United States and the Soviet Union during the 1950s and 1960s until his early death. The lunar and Martian craters Korolev are also named in his honour.^[2] The official naming citation was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 3825}}).^[28]
