Key Information
- Official Status: Operates under the auspices of the International Astronomical Union (IAU) and is hosted by the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.
- Primary Functions
- Data Clearinghouse: Acts as the single central hub for all astrometric (positional) measurements of small solar system bodies.
- Orbit Calculation: Uses high-performance computing to calculate the precise orbits of asteroids and comets to predict future paths.
- Official Designations: Assigns unique alphanumeric identities to newly discovered objects (2026 FB3).
- Impact Alerts: Maintains the NEO Confirmation Page (NEOCP), which alerts astronomers worldwide to newly detected objects that might pose a short-term risk of hitting Earth.
- Funding & Support: Primarily funded by a grant from NASA’s Near-Earth Object Observations (NEOO) program.
- The MPC Catalogue: As of March 2026, the center manages data for over 1.5 million observed small bodies, including more than 887,000 officially numbered minor planets.
- New Digital Tools: Recently introduced a near-duplicate check tool via API to help researchers avoid resubmitting redundant observational data.
