1102 Pepita, provisional designation 1928 VA, is a stony background

rotation period of 5.1 hours.[3]

Orbit and classification

Pepita is a non-

semi-major axis of 3.07 AU). Its orbit has an eccentricity of 0.11 and an inclination of 16° with respect to the ecliptic.[1]

In May 1899, the asteroid was first observed as A899 KB at Harvard's

800). The body's observation arc begins with its official discovery observation at Barcelona.[14]

Physical characteristics

In the

Tholen.[1]

Rotation period and poles

Three rotational

rotation period of 5.1054 hours with a brightness amplitude between 0.31 and 0.36 magnitude.[1][12]

In 2011, a modeled lightcurve using data from the Uppsala Asteroid Photometric Catalogue and other sources gave a concurring sidereal period 5.10532 hours, as well as two spin axes of (25.0°, −34.0°) and (231.0°, −30.0°) in ecliptic coordinates (λ, β).[11]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.1842 and 0.322.[5][6][7][8][9]

The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1991 and a diameter of 39.27 kilometers based on an absolute magnitude of 9.40.[3][7]

Naming

This minor planet was named after the discoverer, Josep Comas i Solà (1868–1937), by the feminine form of his nickname, "Pepito". He was the first director of the discovering Fabra Observatory and founded the Astronomical Society of Spain and America (Spanish: Sociedad Astronomica de España y América, SADEYA).[2]

The official naming citation was mentioned in

Comas Sola.[15]
