6189 Völk (prov. designation: Template:Mp) is a stony Vesta asteroid, approximately Script error: No such module "convert". in diameter, located in the inner regions of the asteroid belt. It was discovered on 2 March 1989, by Belgian astronomer Eric Elst at the La Silla Observatory in northern Chile.[1] The S-type asteroid has a short rotation period of 2.9 hours. It was named for Elisabeth Völk, a staff member at ESO headquarters in Germany.[2]

Classification and orbit

When applying the synthetic hierarchical clustering method to its proper orbital elements, Völk is a core member of the stony Vesta family,[3][4][5] one of the largest families in the inner asteroid belt. It orbits the Sun in the inner main-belt at a distance of 2.0–2.6 AU once every 3 years and 6 months (1,278 days; semi-major axis of 2.3 AU). Its orbit has an eccentricity of 0.13 and an inclination of 6° with respect to the ecliptic.[6] It was first observed as Template:Mp at Palomar Observatory during the second Palomar–Leiden Trojan survey in September 1973, extending the asteroid's observation arc by almost 16 years prior to its official discovery at La Silla.[1]

Naming

This minor planet was named after Elisabeth Völk (born 1946), administrative staff member at ESO's headquarters in Germany, in charge of the ESO Schmidt plates archive, who became a good friend of the discoverer. The naming was independently suggested by astronomer and author of the Dictionary of Minor Planets, Lutz Schmadel.[2] The Template:MoMP was published by the Minor Planet Center on 15 February 1995 (M.P.C. 24766Script error: No such module "Check for unknown parameters".).[7]

Physical characteristics

In the SDSS-based taxonomy, Völk is a common, stony S-type asteroid.[8]

Lightcurve

In September 2015, a rotational lightcurve was constructed from photometric observations by Robert D. Stephens at the Center for Solar System Studies in California Template:Obscode. Lightcurve analysis gave a well-defined rotation period of Script error: No such module "val". hours with a brightness amplitude of Script error: No such module "val". in magnitude (U=3Script error: No such module "Check for unknown parameters".).[9]Template:Efn

Diameter

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures (Script error: No such module "val".) kilometers in diameter and its surface has an outstandingly high albedo of (Script error: No such module "val".),[10] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – in accordance with the LCDB's divergent classification into the Flora family – and calculates a larger diameter of 5.2 kilometers.[11]
