30000 Camenzind, provisional designation 2000 AB138, is a bright background asteroid from the inner region of the asteroid belt, approximately 2.5 kilometers 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.[2]
Orbit and classification
Camenzind is a non-family asteroid from the main belt's background population.[3] 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.[1]
The body's observation arc begins with its first observation as 1991 RQ35 at Palomar Observatory in September 1991.[2]
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.[1][5]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Camenzind measures 2.592 kilometers in diameter and its surface has a high albedo of 0.457.[4] Such a high albedo is typical for E-type asteroids.
Naming
This minor planet was named after American student Kathy Camenzind (born 1996), a 2014-finalist of the Intel science talent search (STS).[2] The official naming citation was published by the Minor Planet Center on 13 June 2014 (M.P.C. 88760).[6]
