Description
We detected the nucleus of Comet 22P/Kopff at 4.87 AU from the Sun with
the two IRS peak-up cameras of the Spitzer Space Telescope on April 19,
2007. Using the thermal model of [Groussin, O., and 15 colleagues, 2007.
Icarus 187, 16 25], we derive a nucleus size of 1.89±0.16 km, in
agreement with [Lamy, P., Toth, I., Jorda, L., Groussin, O., A'Hearn,
M.F., Weaver, H.A., 2002. Icarus 156, 442 455], and a thermal inertia

Minor Bodies of the Solar System
This project studies the physical and compositional properties of the so-called minor bodies of the Solar System, that includes asteroids, icy objects, and comets. Of special interest are the trans-neptunian objects (TNOs), including those considered the most distant objects detected so far (Extreme-TNOs or ETNOs); the comets and the comet-asteroid
