Interstellar Objects

Interstellar objects are celestial bodies that originate from outside of the Solar System and travel through the space between stars. These objects can include comets, asteroids, and other small bodies that condense from interstellar gas and dust or are ejected from their parent star systems. The study of interstellar objects provides valuable insights into the composition, formation, and evolution of planetary systems beyond our own. Notable examples include 'Oumuamua, the first observed interstellar object passing through our Solar System, and Comet 2I/Borisov, which is another interstellar comet that has been identified. Interstellar objects are distinguished from regular asteroids and comets, which are primarily found within the Solar System, by their unique trajectories and origin.
