History and Composition of Comets

The video discusses comets, focusing on their nature as icy remnants from the solar system's formation. It highlights Haley's Comet, predicted by Sir Edmund Haley using Newton's Laws. Comets have elliptical orbits, with Temple One being a short-period comet. NASA's Deep Impact mission aimed to study Temple One by colliding an impactor with it, revealing less water and fine particles of clay, carbonates, sodium, and silicates than expected.
