“8441 Lapponica”的意思、由来-开放百科全书

The asteroid orbits the Sun in the inner main-belt at a distance of 1.9–2.5 AU once every 3 years and 3 months (1,184 days; semi-major axis of 2.19 AU). Its orbit has an eccentricity of 0.14 and an inclination of 5° with respect to the ecliptic. The body's observation arc begins with its first observation as {{mp|1953 EC|1}} at Goethe Link Observatory in March 1953, more than 24 years prior to its official discovery observation.^[1]

Palomar–Leiden Trojan survey

The survey designation "T-3" stands for the third Palomar–Leiden Trojan survey, named after the fruitful collaboration of the Palomar and Leiden Observatory in the 1960s and 1970s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory where astrometry was carried out. The trio are credited with the discovery of several thousand asteroid discoveries.^[26]

Physical characteristics

Rotation period

In 2008, two rotational lightcurves of Lapponica were obtained from photometric observations by French amateur astronomer Pierre Antonini and by Maurice Clark at the Montgomery College Observatory in Maryland. Analysis of the best-rated lightcurve gave a rotation period of 3.27 hours with a consolidated brightness amplitude between 0.29 and 0.50 magnitude ({{small|U=3-/2+}}).^[6]^[9]^[10]

Diameter and albedo

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the parent body of the Flora family – and calculates a diameter of 4.50 kilometers based on an absolute magnitude of 13.9.^[6]

Naming

This minor planet was named for the bar-tailed godwit (Limosa lapponica) a migratory bird of the family Scolopacidae.^[2] The official naming citation was published by the Minor Planet Center on 2 February 1999 ({{small|M.P.C. 33791}}) and revised on 2 April 1999 ({{small|M.P.C. 34089}}).^[35]
