“2759 Idomeneus”的意思、由来-开放百科全书

It orbits the Sun at a distance of 4.8–5.5 AU once every 11 years and 10 months (4,313 days; semi-major axis of 5.19 AU). Its orbit has an eccentricity of 0.07 and an inclination of 22° with respect to the ecliptic. The body's observation arc begins with a precovery taken at Palomar Observatory in April 1954, or 26 years prior to its official discovery observation at Anderson Mesa.^[1]

Physical characteristics

In the SDSS-based taxonomy, Idomeneus is a D-type asteroid.^[17]^[33] Pan-STARRS' survey has also characterized it as a dark D-type, while the Collaborative Asteroid Lightcurve Link (CALL) assumes it to be a C-type.^[16] Its V–I color index of 0.91, however, is typical for most larger D-type Jupiter trojans.^[18]

Rotation period

In May 1991, a rotational lightcurve of Idomeneus was obtained from photometric observations by Stefano Mottola using the now decommissioned ESO 1-metre telescope at La Silla Observatory in Chile, with follow-up observation made in June 1992 and in November 2010. Lightcurve analysis gave a rotation period between 32.38 and 32.4 hours with a brightness amplitude between 0.22 and 0.27 magnitude ({{small|U=2+/2/2}}).^[18]^[11]

Suspected binary and slow rotator

In June 2016, observation by Brian Warner at the Palmer Divide Station {{Obscode|U82}} at the Center for Solar System Studies in California, gave an exceptionally long period {{val|479|5}} hours and an amplitude of {{val|0.19|0.02}} magnitude ({{small|U=2+}}), which makes it a slow rotator.^[18]{{efn|name=lcdb-Warner-2016}}

The observations also indicated that Idomeneus is a binary asteroid with a minor-planet moon in its orbit. The satellite's orbital period is {{val|19.295|0.005}} hours, or alternatively, {{val|32.17|0.02}} hours with a brightness variation of 0.14 magnitude. However, the results are tentative and have not been published in any journal as of 2018.^[18]{{efn|name=lcdb-Warner-2016}}

Diameter and albedo

According to the surveys carried out by the Japanese Akari satellite, the Infrared Astronomical Satellite IRAS, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Idomeneus measures between 52.55 and 61.01 kilometers in diameter and its surface has an albedo between 0.0571 and 0.078.^[8]^[9]^[10] CALL derives an albedo of 0.0521 and a diameter of 60.95 kilometers based on an absolute magnitude of 9.9.^[18]

Naming

This minor planet was named after the Greek hero Idomeneus, who led the Cretan armies to the Trojan War and where he slew many Trojans.^[1] The official naming citation was published by the Minor Planet Center on 20 December 1983 ({{small|M.P.C. 8404}}).^[45]
