Halley

Halley's comet was named after Sir Edmond Halley.

Halley is perhaps the most famous comet in history.

Halley is the comet that proved correct Edmund Halley's prediction that it would reappear.

Comet Halley is responsible for depositing the debris that, when falling through Earth's atmosphere, causes the Orionid meteor showers.

Halley has a highly elongated orbit that takes it very close to the Sun and then flings it out into the outer solar system, well past the orbit of Pluto.

Halley's Comet is the best known because it can be seen with the naked eye as it passes by periodically. It was first noticed more than 2,000 years ago. Astronomers have observed and documented its appearances, which has helped them understand comets in general. The comet was named after 17th-century British astronomer Edmond Halley, who computed the rate of its movement from his 1682 observations and predicted that it would reappear in 1758, long after his death.
