'Charles Thomas Kowal' (born November 8 1940) is an American astronomer.
He discovered two moons of Jupiter: Leda in 1974 and Themisto in 1975, although the latter was lost and not rediscovered until 2000.
He also discovered the unusual asteroid/comet 2060 Chiron in 1977.
Besides Chiron he discovered or co-discovered a number of other asteroids, including notably the Aten asteroid 2340 Hathor; the Apollo asteroids 1981 Midas, 2063 Bacchus, 2102 Tantalus, and (5660) 1974 MA; the Amor asteroids (4596) 1981 QB and (4688) 1980 WF; and the Trojan asteroids 2241 Alcathous and 2594 Acamas.
He also discovered many supernovas in other galaxies, and discovered or co-discovered some comets, including periodic comets 99P/Kowal, 104P/Kowal, 134P/Kowal-Vavrova, 143P/Kowal-Mrkos, 158P/Kowal-LINEAR (and Chiron has the cometary designation 95P/Chiron).
Kowal won the James Craig Watson Medal in 1979.
Also the initial (2004) R. R. Newton Award for Scientific History, for discovering that Galileo had observed Neptune.
