This first release of the Small Body Dynamics Tool (SBDynT) includes our major analysis tools optimized for Main Belt Asteroids and Transneptunian Objects. These tools include calculation of synthetic proper elements and stability indicators; we also provide automated dynamical classifications for TNOs, including detailed resonant identification. SBDynT contains additional useful tools for initializing Rebound simualtions based on any observed small body, including producing clones that sample the small body's orbit-fit uncertainties as given by JPL's Small Body Database and automatically querying JPL Horizons for planet positions at the orbit-fit epoch.
