“4585 Ainonai”的意思、由来-开放百科全书

In 1972, it was first identified as {{mp|1972 LU}} at Crimea–Nauchnij, extending the body's observation arc by 18 years prior to its official discovery observation at Kitami.^[16]

Physical characteristics

Lightcurve

A rotational lightcurve was obtained from photometric observation made at the Via Capote Observatory, California, in June 2008. It showed a longer than-average rotation period of {{val|38.31|0.05}} hours with a brightness amplitude of 0.30 in magnitude ({{small|U=3-}})^[7]

Diameter and albedo

According to observations from the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Ainonai has an albedo of 0.11 with a corresponding diameter of 10.9 kilometers.^[4]^[5] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 15.3 kilometers with an absolute magnitude of 12.8.^[6]

Naming

This minor planet was named after Ainonai, a small Japanese town located near Kitami in eastern Hokkaidō. The minor planets 3785 Kitami and 3720 Hokkaido are named after these two places.^[2] The official naming citation was published by the Minor Planet Center on 21 November 1991 ({{small|M.P.C. 19338}}).^[26]

It was discovered on 16 May 1990, by Japanese amateur astronomers Kin Endate and Kazuro Watanabe at the Kitami Observatory in eastern Hokkaidō, Japan.^[16] It was named for the town of Ainonai located near the discovering observatory.^[2] Orbit and classification Ainonai orbits the Sun in the central main-belt at a distance of 2.1–3.4 AU once every 4 years and 6 months (1,652 days). Its orbit has an eccentricity of 0.24 and an inclination of 11° with respect to the ecliptic.
