Saturn's Trojan Moon Calypso

Saturn XIV


Calypso [ka-LIP-so] and Telesto [tah-LESS-toh] are called the Tethys Trojans because they circle Saturn in the same orbit as Tethys, about 60 degrees ahead of and behind that body. Telesto is the leading Trojan and Calypso is the trailing Trojan. Both were found in 1981 by B. Smith through ground-based observations made in 1980. Calypso is 34 by 22 by 22 kilometers (21 by 14 by 14 miles).
