Why is Halley's comet so important

Answer 1

hey mate here is your answer

Like most comets, it is made of ice, dust, and gas. When Halley's Comet orbits close to the Sun, it has a bright and glowing appearance that can be seen from Earth. It is said that it was first noticed back in 240 BC. In 1705, an astronomer named Edmond Halley discovered that the comet appears every 75 to 76 years.

Answer 2

Halley's Comet was discovered by astronomer Edmond Halley in 1696, who studied the reports of a comet approaching Earth in years 1531, 1607, and 1682. He concluded that these three comets were in fact the same that always returned to Earth, and predicted that the comet would return again in 1758.
