“21062 Iasky”的意思、由来-开放百科全书

This minor planet was named after Australian geophysicist Robert Iasky (born 1956), who discovered the 120-kilometer-sized Woodleigh crater in the Carnarvon Basin of Western Australia while working with the Geological Survey of Western Australia.^[1] The official {{MoMP|21062|naming citation}} was published by the Minor Planet Center on 1 May 2003 ({{small|M.P.C. 48396}}).^[18]

Physical characteristics

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Iasky measures 19.034 kilometers in diameter and its surface has an albedo of 0.063,^[8] which is typical for a carbonaceous C-type asteroid. As of 2018, no rotational lightcurve of Iasky has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.^[21]

In literature

In his 1994 book Pale Blue Dot, Astronomer Carl Sagan speculated on the nature of {{mp|1991 JW|1}} (Iasky), saying it "has an orbit very much like the Earth's and is even easier to get to than 4660 Nereus. But its orbit seems too similar to the Earth's for it to be a natural object. Perhaps it's some lost upper stage of the Saturn V Apollo moon rocket".^[1]

It was discovered on 13 May 1991, by American astronomers Carolyn and Eugene Shoemaker at the Palomar Observatory in California. It was named for Australian geophysicist Robert Iasky.^[1] Orbit and classification Iasky is a non-family asteroid from the main belt's background population.^[5]^[6] It orbits the Sun in the outer asteroid belt at a distance of 2.9–3.1 AU once every 5 years and 4 months (1,940 days; semi-major axis of 3.04 AU). Its orbit has an eccentricity of 0.03 and an inclination of 24° with respect to the ecliptic. The body's observation arc begins in November 1982, with its first observations taken by the Siding Spring Observatory and published with the Digitized Sky Survey later on.^[1] Naming This minor planet was named after Australian geophysicist Robert Iasky (born 1956), who discovered the 120-kilometer-sized Woodleigh crater in the Carnarvon Basin of Western Australia while working with the Geological Survey of Western Australia.^[1] The official {{MoMP\|21062\|naming citation}} was published by the Minor Planet Center on 1 May 2003 ({{small\|M.P.C. 48396}}).^[18] Physical characteristics According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Iasky measures 19.034 kilometers in diameter and its surface has an albedo of 0.063,^[8] which is typical for a carbonaceous C-type asteroid.
