Шаблон:Short description Шаблон:Infobox planet

22740 Rayleigh, provisional designation Шаблон:Mp, is a Zhongguo asteroid from the outermost region of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 20 September 1998, by Belgian astronomer Eric Elst at the La Silla Observatory in Chile. It is one of few asteroids located in the 2 : 1 resonance with Jupiter. The asteroid was named for English physicist and Nobel laureate Lord Rayleigh.[1]

Orbit and classification

Rayleigh is a non-family asteroid from the main belt's background population. It is a member of the small group of Zhongguo asteroids, located in the Hecuba gap (2 : 1 mean motion resonance with Jupiter) near 3.27 AU. Contrary to the nearby unstable Griqua group, the orbits of the Zhongguos are stable over half a billion years.[2][3]

It orbits the Sun in the outer asteroid belt at a distance of 2.5–3.9 AU once every 5 years and 10 months (2,133 days; semi-major axis of 3.24 AU). Its orbit has an eccentricity of 0.21 and an inclination of 3° with respect to the ecliptic.[4] The body's observation arc begins with its observations as Шаблон:Mp at Klet Observatory in September 1986, or 13 years prior to its official discovery observation at La Silla.[1]

Physical characteristics

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Rayleigh measures 9.819 kilometers in diameter and its surface has an albedo of 0.088.[5]

Rotation period

As of 2018, no rotational lightcurve of Rayleigh has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[4][6]

Naming

This minor planet was named after English physicist John William Strutt, 3rd Baron Rayleigh (Lord Rayleigh; 1842–1919), who discovered the noble gas argon and was awarded the Nobel Prize in Physics in 1904 (also see list of laureates).[1] The official naming citation was published by the Minor Planet Center on 1 June 2007 (Шаблон:Small).[7] The lunar crater Rayleigh as well as the crater Rayleigh on Mars are also named in his honor.[8][9]
