Historical comets are celestial objects made of ice, dust, and gas that travel through space. They have been observed for centuries, often appearing bright in the night sky. Notable examples include the Halley's Comet, which returns approximately every 76 years, and the Great Comet of 1811, which was one of the largest comets ever recorded. Comets have played significant roles in various cultures, often seen as omens or signs. Their appearances have been documented in ancient texts, such as the Chinese records from 1059 AD. These observations have contributed to our understanding of the solar system and the behavior of these fascinating objects.
