Comet Hale–Bopp (formally designated C/1995 O1) is a long-period comet that was one of the most widely observed of the 20th century and one of the brightest seen for many decades. [10] [11] [12] Alan Hale and Thomas Bopp discovered Comet Hale–Bopp separately on July 23, 1995, before it became visible to the naked eye.
Alan Hale (born 1958) [1] is an American professional astronomer, who co-discovered Comet Hale–Bopp along with amateur astronomer Thomas Bopp. [2]Hale specializes in the study of Sun-like stars and the search for extra-solar planetary systems, and has side interests in the fields of comets and near-Earth asteroids.
Thomas Joel Bopp (October 15, 1949 – January 5, 2018) was an American amateur astronomer. In 1995, he discovered comet Hale–Bopp; Alan Hale discovered it independently at almost the same time, and it was thus named after both of them. [1] At the time of the comet discovery he was a manager at a construction materials factory and an amateur ...
The Great Comet of 1811, [4] formally designated C/1811 F1, is a comet that was visible to the naked eye for around 260 days, the longest recorded period of visibility until the appearance of Comet Hale–Bopp in 1997.
Comet McNaught as the Great Comet of 2007. A great comet is a comet that becomes exceptionally bright. There is no official definition; often the term is attached to comets such as Halley's Comet, which during certain appearances are bright enough to be noticed by casual observers who are not looking for them, and become well known outside the astronomical community.
Celtic Voices and Hale Bopp, op. 36, are two independent compositions by Graham Waterhouse for string orchestra, which were published together in 1998 by Hofmeister, Leipzig. Celtic Voices was written in 1995, Hale Bopp was written in 1997 inspired by Comet Hale-Bopp , and scored for an additional boy soprano .
More recently, during the passage of Halley's Comet in 1910, Earth passed through the comet's tail, and erroneous newspaper reports inspired a fear that cyanogen in the tail might poison millions, [233] whereas the appearance of Comet Hale–Bopp in 1997 triggered the mass suicide of the Heaven's Gate cult. [234]
On September 26 the comet made its closet approach to Earth at a distance of about 1.15 AU; for a great comet this distance is unusually large — only two other known great comets failed to come closer than 1 AU to Earth — namely, the Great Comet of 1811 and Comet Hale-Bopp. [6]
