Armchair Astronomer — Comets: Interstellar Vagabonds

Ken Vanlew, retired astronomy & physics teacher, joins us via Zoom to share his insights. As of 2026, only 3 interstellar comets have been discovered. These bodies from outer space pass by the Sun and planets on a one-time trip never to return. They race through the solar system on hyperbolic orbits too fast to be captured by the Sun’s gravity. Join us to learn more about these interstellar vagabonds with Ken.
