    Aliens Hiding in Plain Sight? Interstellar Comets, Rocks..

    The authors , Tom Hands, Walter Dehnen, calculate the capture rate, by Jupiter, predominantly, of interstellar comets (like Borisov) and rocks, (like Oumuamua). They come up with our known long period objects could contain as many as 100 comets, and 100,000 rocks from alien solar systems. That'd be worth checking up closer on a pass-by mission. See:https://arxiv.org/abs/1910.06338

    What's with "Aliens" in your title? A casual reader might envision intelligent interstellar spacefarers. All the linked article mentions is capture of interstellar comets and rocks.

    Pardon me, I just found the subtitle "4.1 Detectability of alien stowaways" deep in the full paper. They were using "alien" for interstellar objects and "native" for those originating in the solar system.
