30000 Camenzind (provisional designation 2000 AB₁₃₈) is a very bright background asteroid from the inner region of the asteroid belt, approximately 2.6 kilometers (1.6 miles) in diameter. It was discovered on 4 January 2000, by astronomers of the Lincoln Near-Earth Asteroid Research program conducted at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States. The asteroid was named for 2014-ISTS awardee Kathy Camenzind.

Orbit and classification

Camenzind is a non-family asteroid from the main belt's background population. It orbits the Sun in the inner asteroid belt at a distance of 2.1–2.4 AU once every 3 years and 5 months (1,247 days; semi-major axis of 2.27 AU). Its orbit has an eccentricity of 0.08 and an inclination of 7° with respect to the ecliptic. The body's observation arc begins with its first observation as 1991 RQ₃₅ at Palomar Observatory in September 1991.

Naming

This minor planet was named after American student Kathy Camenzind (born 1996), a 2014-finalist of the Intel science talent search (STS). The official naming citation was published by the Minor Planet Center on 13 June 2014 (M.P.C. 88760).

Physical characteristics

Rotation period

As of 2018, no rotational lightcurve of Camenzind has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Camenzind measures 2.59 kilometers in diameter and its surface has a high albedo of 0.457. Such a high albedo is typical for E-type asteroids.
