5655 Barney, provisional designation 1159 T-2, is a Maria

rotation period of 2.66 hours.[4]

Orbit and classification

Barney is a core member of the

semi-major axis of 2.58 AU). Its orbit has an eccentricity of 0.04 and an inclination of 14° with respect to the ecliptic.[2]

Discovery

Barney was discovered on 29 September 1973, by Dutch astronomer couple

precoveries were taken prior to its discovery. The body's observation arc begins with its official discovery observation.[1]

Palomar–Leiden survey

The

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.[11]

Physical characteristics

Barney has been characterized as a stony S-type asteroid in the SDSS taxonomy of the Moving Object Catalog (MOC) and by the survey conducted by Pan-STARRS.[4][8][9]

Rotation period

In August 2010, a rotational

U=2).[4][7]

Diameter and albedo

According to the survey carried out by the

albedo of 0.256.[5][6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a stony asteroid of 0.20 and calculates a diameter of 6.11 kilometers based on an absolute magnitude of 13.43.[4]
