Welcome to MDS: MPC Data Services
MDS encapsulates the next generation MPC web services, both interactive and programmatic. Our new data-centric
web apps and APIs will be hosted here on the "data" subdomain.
Summary of Where Are My Observations - SWAMO
SWAMO lets you explore the outcomes of all submissions over the MPC's history at a month-level granularity,
and the SWAMO-R dashboard lets you explore the outcomes of the past six months worth of submissions at a
day-level granularity. Visit the about page for more information.
MPC Explorer
MPC Explorer is a user-friendly web application that allows you to search for an object, resolve its identity,
and retrieve its designation information, observations, orbit, and associated MPECs.
You can also search for NEOCP objects, view lists of objects, and check for near-duplicate observations in our database.
The Explorer leverages the latest version of the Designation Identifier API
and other APIs.
Orbit Comparison Tool for NEOs
This tool allows you to compare the orbital parameters that are present in MPC's MPCORB.dat files with
JPL's values for the same objects.
(Alpha) MPC Summary
The MPC Summary page provides an overview of the MPC's data holdings.
(Alpha) MPC Lists
This lists frontend is meant to replace the lists available here.
