Enceladus is only 504 kilometers (313 miles) across, small enough to fit within the length of the United Kingdom, as illustrated here.
(The intriguing icy moon also could fit comfortably within the states of Arizona or Colorado.)
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
