The International Astronomical Union's Minor Planet Center (MPC) is responsible for the designation of minor bodies found within our solar system. This includes minor planets, comets, and natural satellites. The MPC is also responsible for collecting, computing, checking, and disseminating astrometric observations and orbital information for those minor bodies.
The Asterank MPC API enables users to apply constraints to the more than 600,000 asteroids documented in the MPC's MPCORB.DAT files. Because the Asterank database runs on MongoDB, queries must use Mongo's JSON format. Information in the Asterank MPC database is updated nightly.
The following is a list of historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at email@example.com
So far, we don't have a record of any changes to this API
