Interstellar objects as a research area focus on the detection, characterization, and dynamical analysis of solid bodies that originate outside a planetary system and traverse or enter another, such as the Solar System. This field integrates observational astronomy, celestial mechanics, planetary science, and astrochemistry to constrain their trajectories, compositions, sizes, shapes, rotational states, and possible formation environments. Research investigates their implications for planetesimal formation, mass loss from planetary systems, galactic dynamical processes, and the transfer of material between stellar systems, as well as optimizing observational strategies and instrumentation for their rapid identification and follow-up before they exit observational reach.
