Sleuth: The Palomar Planet Finder

The Palomar Observatory's smallest telescope is known as Sleuth. Sleuth is a robotic telescope dedicated toward the search for planets around other stars. Specifically it is searching  for signs of gas-giant planets passing directly in front of  (transiting) a star.
 

To do this Sleuth nightly monitors roughly 10,000 stars 6 degree square field-of-view in the hunt for these transiting extrasolar gas-giant planets. This planet finder is the third instrument in a network that also contains STARE (located in Tenerife) and PSST (located in northern Arizona). Candidates identified by Sleuth will be observed by our automated follow-up telescope (currently under construction in the same enclosure) to rule out most forms of false positives resulting from eclipsing binaries.
