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. 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.

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. 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. The body's observation arc begins with its official discovery observation by Franz Kaiser at the Heidelberg Observatory on 26 August 1913.

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).

Physical characteristics

In the Bus–Binzel SMASS classification, Vinifera is an X-type asteroid.

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). 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).

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.

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). 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.

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.
