Did We Just Discover More ‘Oumuamua Type Objects?

We know that there are lots of asteroids and comets in the solar system, and we’ve even landed a spacecraft on a comet, so we know a reasonable amount about these objects. However in 2017, something happened that had never happened before. We detected an object that looked like a comet, but its motion and trajectory indicated that it came from outside of our solar system. This object was named ‘Oumuamua, and we now understand that it is an exocomet, having originated in another system, traveling for millions of years through interstellar space before paying us a visit.

Oumuamua and Borisov are not the only interstellar interlopers. We know of many more. Here’s what we know about them so far.
