OrbFit: Open-Source Asteroid Orbit Determination Software

OrbFit is a comprehensive open-source software suite for the orbital determination of asteroids and comets, developed by the University of Pisa and distributed under GNU GPL.
SpaceDyS plays a key role within the international OrbFit Consortium, contributing to continuous development, maintenance and technical support.
Core Capabilities

• High-precision orbit propagation
• Ephemeris computation
• Outlier rejection
• Impact monitoring through the CLOMON2 system

OrbFit has been adopted by the Minor Planet Center, the official international authority supported by the International Astronomical Union (IAU) and funded by NASA for the global management of asteroid data.

Through its involvement in OrbFit, SpaceDyS strengthens its leadership in asteroid dynamics and planetary defense software development.
