734 Benda (

rotation period of 7.1 hours. It was named after the discoverer's wife, Anna Benda.[2]

Orbit and classification

Benda is a non-

semi-major axis of 3.15 AU). Its orbit has an eccentricity of 0.10 and an inclination of 6° with respect to the ecliptic.[3] The body's observation arc begins at the discovering Vienna Observatory on 23 February 1920, almost eight years after its official discovery observation.[1]

Naming

This

naming was erroneously attributed to the Czech composer Karel Bendl (1838–1897) in previous editions of the Dictionary of Minor Planet Names.[2]

Physical characteristics

Benda is an

Small Solar System Objects Spectroscopic Survey (S3OS2).[5][12] In agreement with its low albedo (see below), this object has also been classified as a C-type and P-type asteroid.[13]

Rotation period

In October 2013, a rotational

In August 1995, a first period of 7.114 hours was determined by

Diameter and albedo

According to the surveys carried out by the

albedo of (0.054±0.010), (0.0464±0.004) and (0.044±0.002), respectively.[7][8][9] The Collaborative Asteroid Lightcurve Link derives a low albedo of 0.0387 and a diameter of 70.71 kilometers based on an absolute magnitude of 9.9.[13]

Alternative mean-diameters published by the WISE team include (64.45±17.46 km), (67.318±0.267 km),

asteroid occultations on 4 April 2009 and on 3 September 2013, gave a best-fit ellipse dimension of (70.0 km × 70.0 km) and (73.0 km × 73.0 km), respectively, each with a low quality rating of 1.[5] These timed observations are taken when the asteroid passes in front of a distant star.[5]
