Exploring Interstellar Objects in Our Solar System

The video discusses interstellar objects, focusing on 'Oumuamua and Comet Borisov, which are visitors from outside our solar system. It explores the potential of interstellar immigrants like Kaʻepaokaʻāwela and Comet Hyakutake, and the journey of Comet Bowell towards interstellar space. The video also highlights the educational platform Brilliant, which offers interactive lessons in science and math.
