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. [11] [12] [13] 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.
The following is a list of Halley-type comets (HTCs), which are periodic comets with an orbital period between 20 and 200 years, often appearing only once or twice within one's lifetime.
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 ...
Eugene Merle Shoemaker (April 28, 1928 – July 18, 1997) was an American geologist. He co-discovered Comet Shoemaker–Levy 9 with his wife Carolyn S. Shoemaker and David H. Levy.
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.
They are in separate studios in Mexico City, presumably working on their upcoming album, from which they have released a slew of singles this past year, including “Mar Universal,” “Siento La ...
For instance, comet Hale-Bopp was last seen in 2013 at magnitude 24 [2] and continues to fade, making it invisible to all but the most powerful telescopes. The maximum extent of the region in which the Sun's gravitational field is dominant, the Hill sphere, may extend to 230,000 astronomical units (3.6 light-years) as calculated in the 1960s. [3]
