10003 Caryhuang[1] (provisional designation 1971 UD1) is a medium-sized asteroid that orbits between Mars and Jupiter located in the main part of the asteroid belt. It was named after Cary Huang from his contributions to The Scale of the Universe, an online interactive scale tool. It was discovered in 1971, and has orbited approximately 2,800 times as of June 2025.[2][3][4]

History

Caryhuang was first discovered and observed on October 26, 1971, and was discovered by Luboš Kohoutek at the Hamburg-Bergedorf Observatory.[3][5]

In 2021, the International Astronomical Union named the asteroid Caryhuang after animator and educator Cary Huang, who made The Scale of the Universe with twin brother Michael Huang.[6][7]
