OSSOS TNOdb

welcome to the discovery database

Nearly 1000 TNOs known to inhabit the outer Solar System have been discovered by OSSOS (or earlier CFEPS). Here we provide additonal information about specific objects, a complete listing of our discoveries that can be associated to our well-measured, or characterized, detection efficiency and modelled using our Survey Simulator.

We provide the OSSOS Master File and the CFEPS Master File, which give the naming linkages between internal project names and the Minor Planet Center designations. (These linkages to OSSOS/CFEPS names is highly valuable as this provides the link to the 'block' of sky coverage in which the object was found. For each 'block' of sky coverage we provide a precise measurement of our object detection efficency as a function of object brightness and search rate.) The above tables identify OSSOS+CFEPS internal designations with MPC designations.

In addition the CFEPS Summary file and the OSSOS E+O Summary file (the publicly available component of OSSOS) provide lists of all OSSOS+CFEPS detections, their orbital classification, and their barycentric orbital elements. Such a table is, by far, best used in conjunction with the OSSOS Survey Simulator.
