The Fascinating World of Comets

The video tutorial discusses comets, their composition, and their role in the solar system. Comets are icy bodies that release gas and dust, forming tails when near the sun. They originate from the Oort cloud and may have contributed to Earth's water and organic molecules. Historically, comets were seen as omens, but they are natural phenomena. Halley's Comet, visible every 76 years, is a notable example, named after astronomer Edmund Halley.
