  • MPC Archive Statistics

    The Minor Planet Center maintains dynamic archives of observations and orbits of comets and minor planets. The archives currently contain 111145491 observations and 639091 orbits (a more detailed breakdown of these figures is available below).


    Observations

    The listing below shows the increase in the size of the observational archive. A grand total (including both comets and minor planets) is given at the completion of each batch of Minor Planet Circulars, as well as individual totals for each class of object. Each class of object is further subdivided: minor planets are divided into numbered and unnumbered objects; comets are divided into numbered periodic and other comets (the other comets also includes the unnumbered periodic comets).

    Note that after 2003 March 18, the counts refer to the number of records in the observational database, not the number of unique observations. A number of observations (approximately 10000 at the above-mentioned date) occupy two records. Prior to the above date, the count is of unique observations.

    The number of observations increases both as a result of current observations made by numerous observers worldwide and as a result of the inclusion of early observations extracted (and in many cases rereduced with modern star positions) from the literature by the Minor Planet Center.


    Orbits And Names

    The listing below shows the increase in the size of the orbital archive for minor planets. A grand total at the completion of each batch of Minor Planet Circulars is given (note that no minor-planet orbits are published when a mini-batch is prepared). This total is the sum of the numbered objects, the multiple-opposition orbits (including the one-opposition orbits computed with consideration of perturbations) and single-opposition orbits. The number of named minor planets is shown in the last column.
