32008 Adriángalád (

rotation period of 3.0 hours. It was named for Slovak astronomer Adrián Galád.[1] Its 1.6-kilometer sized minor-planet moon was discovered in August 2007.[5]

Orbit and classification

Adriángalád is a non-

clan of stony bodies in the inner asteroid belt.[7]

It orbits the Sun in the

semi-major axis of 2.19 AU). Its orbit has an eccentricity of 0.19 and an inclination of 6° with respect to the ecliptic.[2] The body's observation arc begins almost 9 years prior to its official discovery observation, with a precovery taken by the Steward Observatory's Spacewatch survey at Kitt Peak in November 1991.[1]

Physical characteristics

In the SDSS-based taxonomy, Adriángalád has been characterized as a bright V-type asteroid.[3][8]

Satellite

During Pravec's photometric observations it was revealed that Adriángalád is a synchronous binary system, with a minor-planet moon orbiting it every 40.24±0.02 hours.[6] It received the provisional designation S/2007 (32008) 1. The satellite measures approximately 40% of that of its primary,[6] with published diameters of 1.62 and 1.69 kilometers, respectively.[3][5] The companion orbits its primary at an estimated average distance of 13 kilometers only.[5]

Diameter and albedo estimate

A combined effective diameter of 4.35 kilometers for the system has been published based on secondary-to-primary diameter-ratio of 0.40, that is, 4.04 km for the primary, and 1.62 km for the secondary. The assumed

albedo for the primary is 0.16.[3] Johnston's archive uses the same ratio of 0.40 and estimates and effective diameter of 4.56 kilometers with 4.23 and 1.69 kilometers for the primary and secondary, respectively.[5] The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.24 – derived from 8 Flora, the Flora family's largest member – and calculates a diameter of 3.07 kilometers with an absolute magnitude of 14.73.[7]
