(13219) Cailletet is a main outer belt asteroid that was discovered on June 30, 1997 as part of the University of Arizona Spacewatch project at the Kitt Peak National Observatory ( IAU code 691). The asteroid had already been sighted: on September 2, 1986 under the provisional designation 1986 RZ 3 at the French Observatoire de Calern and on January 18 and 19, 1994 (1994 BK 5 ) at the Karl Schwarzschild Observatory in the Tautenburg Forest .

The mean diameter of the asteroid was calculated very roughly to be 16.073 km (± 7.260).

(13219) Cailletet was named on March 18, 2003 after the French physicist Louis Paul Cailletet (1832–1913), who was the first to liquefy permanent gases such as oxygen , nitrogen and hydrogen . For example, liquid nitrogen is used by astronomers to cool image detectors.
