Show affiliationsWe present the results of a wide-field survey for distant Sedna-like bodies in the outer solar system using the 1.2 m Samuel Oschin Telescope at Palomar Observatory. We searched ~12,000 deg2 down to a mean limiting magnitude of 21.3 in R. A total number of 53 Kuiper Belt objects and Centaurs have been detected, 25 of which were discovered in this survey. No additional Sedna-like bodies with perihelia beyond 70 AU were found despite a sensitivity to motions out to ~1000 AU. We place constraints on the size and distribution of objects on Sedna orbits.
