29292 Conniewalker, provisional designation 1993 KZ1, is a bright stony asteroid and slow tumbler from the inner regions of the asteroid belt, about 4.6 kilometers in diameter. It was discovered by American female astronomer Carolyn Shoemaker and Canadian astronomer David H. Levy at the U.S. Palomar Observatory, California, on 24 May 1993.[8]

The S-type asteroid is a member of the Phocaea family. It orbits the Sun at a distance of 1.9–2.8 AU once every 3 years and 7 months (1,315 days). Its orbit shows an eccentricity of 0.20 and an inclination of 26 degrees from the plane of the ecliptic.[1]

In 2011, two photometric light-curve analysis at the U.S. Via Capote Observatory in California and at the Ondřejov Observatory, Czech Republic, rendered a rotation period of 30.6 and 30.5 hours, with a brightness amplitude of 0.62 and 0.63 in magnitude, respectively.[6][a] The asteroid is a tumbler. The best light-curve result (U=3-) was achieved during 22 sessions over a 46-day period where the body showed a non-principal axis rotation (NPAR).[6] The slow tumbler had previously been a target in ASU's Photometric Survey for Asynchronous Binary Asteroids.[9]

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), the body measures about 4.58 kilometers in diameter and has a very bright surface albedo of 0.36, while a later revision of the WISE data gave a lower but still high albedo of 0.31 with a diameter of 4.57 kilometers.[4][5] The Collaborative Asteroid Lightcurve Link (CALL) agrees on the revised data which also includes a raise of the body's absolute magnitude from 13.4 to 13.59.[3]

The minor planet was named in honor of American female astronomer Connie Walker (b. 1957) who has studied star formation in galaxies of different ages. She is best known for her education of young people in astronomy throughout southern parts of the U.S. state of Arizona. Her insights into how children can be motivated to enjoy the stars has led to the great success of Project Astro-Tucson.[2]
