Halley's Comet is named after a guy's last name. He was Edmund HALLEY.
The girl's name 'Haley' does not come into question.
Halley's Comet (that's easy, right?). Although it had been observed before, Halley was the first to discover that it was the same comet that returned at regular intervals, instead of a different object each time, and calculated its orbital period. There also exists a lunar crater named Halley.
There is no specific ticker symbol for Comet as it is not a publicly traded company. If you are referring to any company named "Comet", you would need to specify which particular company you are inquiring about to find its ticker symbol.
I assume you are asking about Shoemaker-Levy 9. This comet smashed into Jupiter and disturbed the appearance of Jupiter for a time. Perhaps what makes this unique is that the astronomers for whom this comet was named predicted its demise and observed the detritus kicked up. That was a first. As for the event itself - the plunging of a comet into the gas giant Jupiter - that could hardly be called unique. As the largest planet in our solar system, Jupiter absorbs a lot of blows and protects the inner planets. Without Jupiter, Earth would be much more pockmarked by meteors, comets and other orbiting objects whose paths tangle with the orbit of the Earth. For an excellent - and much fuller explanation - look up "Comet Shoemaker-Levy 9" in wiki answers.
Comets have been seen in the skies since very ancient times. There is no specific date for their discovery. They have been known since people first came to be. The appearance of comets through out history have been used as harbingers of change usually of the negative kind. Comets are considered by astronomers to be dirty snowballs composed of frozen water, gases such as CO2, methane and dust. As comets approach the Sun, they usually develop a tail which is a result of the solar wind striking the comet causing the frozen gases and water to evaporate off the main body of the dirty snow ball forming a feather like plume of trailing gas. The dirty part usually consists of silicate materials. For more about comet compositions, see Sources and Related Links (further down this page). As the comet approach the Sun the tail is behind it and as it circles behind the Sun and then leaves the Sun the tail is before or ahead of it, which is a result of the solar wind in both situations. One way of classifying comets is on the basis of their orbit: short term and long term. Short term comets are trapped gravitationally by the sun and have periodic orbits of about 200 years. The most famous of these is Halley's comet which may have been the comet seen in 1066 at the battle of Hastings. Chinese observers noted it in 619 BC. It has a period of 76 years. For a more complete story about Halley's comet, see Sources and Related Links (further down this page). For a more complete story about Chinese and Babylonian observations, see Sources and Related Links (further down this page). Short term comets are believed to have their region of origin in the part of our solar system's plane of the ecliptic called the Kuiper belt. The inner edge of KB includes the orbit of Mars out to a distance of about 30 AU. 1 AU is the distance from the Earth to the Sun. The second category of comets are called long term comets for their orbital period if they have one is so long that it periodicity is not recognized. The region of origin of long term comets is believed to be the region of the solar system called the Oort cloud. It is the spherical region around the Sun from about 5000 Au to 100,000 AU
The experiment that confirmed Halley's hypothesis regarding the nature of comets was conducted by Edmond Halley himself in 1705. He predicted that the Great Comet of 1682 would return in 1758, based on its orbit. When the comet reappeared as predicted, it was named Halley's Comet in his honor, validating his theory that comets could have predictable orbits similar to planets. This observation established the notion that comets are not random but instead follow specific paths through the solar system.
Edmund Halley did not invent anything, but he was a British astronomer known for calculating the orbit of the comet that now bears his name. Halley's Comet, which passes by Earth approximately every 75-76 years, was the first comet to be recognized as periodic.
Edmund Halley was the fellow who first realized that the historical accounts of comets seemed to show that they were not solitary events; that they came back into view on a regular schedule. Examining the records, Halley calculated the probable orbit of the comet and concluded that the comet of 1682 was probably the same comet that had been seen in 1607 and before that in 1531. Halley predicted that the comet would once again be visible in 1758. When it was observed in December, 1758, it was dubbed "Halley's Comet", a title it retains.To astronomers, Halley's Comet is called "1P/Halley"; the 1P indicates that in the catalog of comets, this is the first entry and that it is "Periodic".
The first "certain" appearance of Halley's Comet is from 240 BC, in the Chinese chronicle Records of the Grand Historian or Shiji, which describes a comet that appeared "in the east and moved north".
Halley's Comet is arguably the most famous comet in history. It is visible from Earth every 76 years, making it a well-known and anticipated astronomical event for centuries. Its appearances have been recorded since ancient times, with the earliest known sighting dating back to 240 BC.
That is Halley's comet, named after English astronomer Edmond Halley,
Halley's comet - which returns to our solar system approximately every 75 years - is one example, named after it's discoverer Edmund Halley. Another notable example is Shoemaker-Levy 9. It was observed orbiting the planet Jupiter, but the orbit was decaying - leading to the prediction that it was to crash into Jupiter's surface.
The Russians named their space probes that visited Halley's Comet in the mid-1980s as Vega 1 and Vega 2. These probes were part of an international effort involving the Soviet Union, the European Space Agency, and other countries to study the famous comet.
Uranus is one of the seven heavenly bodies named after its discovery. It was the first planet discovered with a telescope.
its called a dirty snowball because of the wau it looks
Edmond Halley was the first to have a comet named after him following his prediction of the return in 1758 of the comet now named after him. Many other astronomers, both amateur andd professional, have been similarly honored since then.
The Halley's comet was named after Edmond Halley, the English astronomer who was the first to determine the comet's periodicity. He first sighted it in 1705.
Comet West is named after its discoverer, Richard M. West, who observed the comet in 1975.
