759 Vinifera (prov. designation: Шаблон:Mp or Шаблон:Mp) is a large background asteroid from the central regions of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 26 August 1913, by German astronomer Franz Kaiser at the Heidelberg-Königstuhl State Observatory in southwest Germany.[1] The dark X-type asteroid has a rotation period of 14.2 hours and a heavily elongated shape. It was named after the plant species vitis vinifera, also known as the common grape vine.[2]
Orbit and classification
Vinifera is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.[3][4] It orbits the Sun in the central asteroid belt at a distance of 2.1–3.2 AU once every 4 years and 3 months (1,548 days; semi-major axis of 2.62 AU). Its orbit has an eccentricity of 0.21 and an inclination of 20° with respect to the ecliptic.[5] The body's observation arc begins with its official discovery observation by Franz Kaiser at the Heidelberg Observatory on 26 August 1913.[1]
Naming
This minor planet was named after the plant vitis vinifera, the common grape vine, to honor the discoverer's ancestors who were winemakers. The Шаблон:MoMP was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (Шаблон:Small).[2]
Physical characteristics
In the Bus–Binzel SMASS classification, Vinifera is an X-type asteroid.[5][4]
Rotation period
In September 2002, a rotational lightcurve of Vinifera was obtained from photometric observations by Maurice Clark at the Goodsell Observatory Шаблон:Obscode in Minnesota. Lightcurve analysis gave a well-defined rotation period of Шаблон:Val hours with a brightness variation of Шаблон:Val magnitude (Шаблон:Small).[6] Other observation by Jean-Gabriel Bosch, Jacques Michelet and René Roy (2002), Brian Uzpen and Steven Kipp (2002), as well as René Roy and Eric Barbotin (2019), gave nearly identical periods of Шаблон:Val, Шаблон:Val and Шаблон:Val hours with an amplitude of Шаблон:Val, Шаблон:Val and Шаблон:Val magnitude, respectively (Шаблон:Small).[7][8]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), Vinifera measures (Шаблон:Val), (Шаблон:Val) and (Шаблон:Val) kilometers in diameter and its surface has an albedo of (Шаблон:Val), (Шаблон:Val) and (Шаблон:Val), respectively.[9][10][11][12]
Alternative mean-diameter measurements published by the WISE team include (Шаблон:Val), (Шаблон:Val), (Шаблон:Val) and (Шаблон:Val) with corresponding albedos of (Шаблон:Val), (Шаблон:Val), (Шаблон:Val) and (Шаблон:Val).[4][13] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0500 and a diameter of 45.07 kilometers based on an absolute magnitude of 10.6.[13]
On 13 January 2002, an asteroid occultation of Vinifera gave a best-fit ellipse dimension of (Шаблон:Val), with a quality rating of 2. Lower rated measurements on 3 October 2011 and on 20 November 2015, gave an ellipse dimension of (Шаблон:Val) and (Шаблон:Val), respectively. These timed observations are taken when the asteroid passes in front of a distant star.[4]
