Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. 17681 Tweedledum (1997 AQ6) is an inner main-belt asteroid discovered on January 6, 1997 by T. Urata at the Nihondaira 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.
