This figure illustrates how an interstellar object is rapidly approaching our solar system. Ejected from its home planet system long ago, the object traveled through interstellar space for billions of years before passing briefly in our cosmic neighborhood. The Robin Observatory will reveal many of these unknown interstellar visitors.
