3267 Glo, provisional designation Шаблон:Mp, is an eccentric Phocaean asteroid and sizable Mars-crosser from the inner regions of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 3 January 1981, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona.[1] It was later named after American astronomer Eleanor Helin.[2]
Orbit and classification
Glo is an eccentric member of the Phocaea family (Шаблон:Small),[3] that orbits the Sun in the inner asteroid belt at a distance of 1.6–3.0 AU once every 3 years and 7 months (1,299 days; semi-major axis of 2.33 AU). Its orbit has an eccentricity of 0.30 and an inclination of 24° with respect to the ecliptic.[4]
The body's observation arc begins with its official discovery observation at Anderson Mesa in January 1981.[1]
Physical characteristics
The asteroid has been characterized as an L- and S-type asteroid by Pan-STARRS large-scale survey.[5]
Spectral type
PanSTARRSШаблон:' photometric survey, has characterized Glo as a LS-type asteroid, a transitional spectral type between the common S-type and rather rare L-type asteroids,[5] which have very different albedos, from as low as 0.039 to as high as 0.383.[6]
Rotation period
A rotational lightcurve of Glo was obtained from photometric observations by Czech astronomer Petr Pravec at Ondřejov Observatory in January 2006. Lightcurve analysis gave a well-defined rotation period of 6.8782 hours with a brightness variation of 0.33 magnitude (Шаблон:Small).[7]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Glo measures 6.45 and 13.56 kilometers in diameter and its surface has an albedo of 0.061 and 0.26, respectively.[8][9] The Collaborative Asteroid Lightcurve Link agrees with IRAS and derives a similar albedo of 0.0725 and a diameter of 13.59 kilometers with an absolute magnitude of 12.8.[7]Шаблон:Efn
Naming
This minor planet was named in honor of Eleanor "Glo" Helin (1932–2009), who was a planetary scientist at JPL and a prolific discoverer of minor planets.[2] The official naming citation was published by the Minor Planet Center on 13 February 1987 (Шаблон:Small).[10]
