Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. 1922 Zulu (1949 HC) is an outer main-belt asteroid discovered on April 25, 1949 by Ernest Leonard Johnson at Johannesburg (UO). It is one of very few asteroids located in the 2 : 1 mean motion resonance with Jupiter. This asteroid was lost shortly after discovery (see Lost asteroid), and only rediscovered in 1974 by Richard Eugene McCrosky , Cheng-yuan Shao and JH Bulger based on a predicted position by C. M. Bardwell of the Cincinnati Observatory. Asteroids (from Greek ἀστήρ 'star' and εἶδος 'like, in form') are a class of Small Solar System Bodies in orbit around the Sun. They have also been called planetoids, especially the larger ones. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disk of a planet and was not observed to have the characteristics of an active comet, but as small objects in the outer Solar System were discovered, their volatile-based surfaces were found to more closely resemble comets, and so were often distinguished from traditional asteroids.
