Английская Википедия:1767 Lampland
1767 Lampland, provisional designation Шаблон:Mp, is an Eoan asteroid from the outer regions of the asteroid belt, approximately 15 kilometers in diameter. It was discovered on 7 September 1962, by astronomers of the Indiana Asteroid Program at Goethe Link Observatory in Indiana, United States.[1] The asteroid was named after American astronomer Carl Lampland.[2]
Orbit and classification
Lampland a member the Eos family (Шаблон:Small), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids.[3][4]Шаблон:Rp It orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,915 days). Its orbit has an eccentricity of 0.10 and an inclination of 10° with respect to the ecliptic.[5]
The asteroid was first identified as Шаблон:Mp at Uccle Observatory in September 1941. The body's observation arc begins with a precovery at Palomar Observatory in August 1951, more than 11 years prior to its official discovery observation at Goethe Link.[1]
Physical characteristics
In the Tholen classification, its spectral type is ambiguous, closest to the X-type asteroid and with some resemblance to the C-type asteroids,[5] while the overall spectral type of the Eos family is that of a K-type.[4]Шаблон:Rp
Rotation period
As of 2017, no rotational lightcurve of Lampland has been obtained from photometric observations. The asteroid's rotation period, poles and shape remain unknown.[6]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Lampland measures 15.448 kilometers in diameter and its surface has an albedo of 0.116.[7][8]
Naming
This minor planet was named after American astronomer Carl Lampland (1873–1951), a graduate of Indiana University, best known for his radiometric measurements of planetary temperatures.[2]
Lampland is also honored by a lunar and by a Martian crater. The name was proposed by Frank K. Edmondson, who initiated the Indiana Asteroid Program.[2] The official Шаблон:MoMP was published by the Minor Planet Center on 20 February 1971 (Шаблон:Small).[9]
