What we learned from the first interstellar comets, ‘Oumuamua and Borisov, and what we can do with the next ones
Main list: Physics and Astronomy Colloquia
In 2017 a strange object was discovered by near-Earth asteroid surveys, with the appearance of a small asteroid, but an orbit that showed it to have come from another star. I will describe what we learned about this object, called ‘Oumuamua, and what we are now learning about the second interstellar object, comet Borisov, which was discovered in September this year and is currently being observed as it approaches the Sun. In addition to what we can measure with telescopes, I will also describe a newly approved ESA space mission that may one day investigate an interstellar object up close: Comet Interceptor.
