Halley's Comet, officially designated 1P/Halley and also referred to as Comet Halley after Edmond Halley, is a comet that can be seen every 75-76 years. It is the most famous of all periodic comets. Although in every century many long-period comets appear brighter and more spectacular, Halley is the only short-period comet that is visible to the naked eye, and thus, the only naked-eye comet certain to return within a human lifetime.[2] Its many appearances over the centuries have had a notable effect on human history, despite the fact that they were not recognized as the same object until the 17th century. Halley's Comet last appeared in the inner Solar System in 1986, and will next appear in mid 2061.

The most standard pronunciation of "Halley" — and the pronunciation that the astronomer himself probably used — is [hæli] (IPA), to rhyme with "valley". The once-standard alternate pronunciation [heɪli] (to rhyme with "Bailey") led to rock and roll singer Bill Haley naming his band Bill Haley and the Comets.

Comet Hale-Bopp (formally designated C/1995 O1) was probably the most widely observed comet of the 20th century, and one of the brightest seen for many decades. It was visible to the naked eye for a record 18 months, twice as long as the previous record holder, the Great Comet of 1811.

Hale-Bopp was discovered on 23 July 1995 at a very large distance from the Sun, raising expectations that the comet could become very bright when it passed close to the Sun. Although comet brightnesses are very difficult to predict with any degree of accuracy, Hale-Bopp met or exceeded most predictions for its brightness when it passed perihelion on April 1, 1997. The comet was dubbed the Great Comet of 1997.

The passage of Hale-Bopp was notable also for inciting a degree of panic about comets not seen for decades. Rumours that the comet was being followed by an alien spacecraft gained remarkable currency, and inspired a mass suicide among followers of the Heaven's Gate cult.
