Halleyâ??s comet is named after English astronomer Edmond Halley. Halley examined reports of a comet approaching Earth in 1531, 1607 and 1682 and concluded that these three comets were actually the same comet returning over and over again. He then predicted the comet would come again in 1758.

French Revolution Rodespirre?
Was born on 6 May 1758 and was guillotined on 28 July 1794. He may have been the only person guillotined face up so that he could see the blade. He had previously attempted suicide, but only managed to shatter his jaw.
Who Maximilian Robespierre?
Maximillien Robespierre, nicknamed "the Incorruptible," was the leader of the Jacobins who took over the leadership of France during the French Revolution. He and the other committee members ordered the execution of the King, Louis XVI, for treason in January 1793.Robespierre, as an enlightened thinker, brought revolutionary ideas of equality, liberty and fraternity to the minds of the French people already put under pressure by poverty, exacerbated by an incapable king and an exorbitant queen.During the revolution, he also made France a secular state. He attempted to rename the months of the year and make 1794 the first year of French history. This did not catch on though, and his attempt to institute a new "festival of the saint" was also unsuccessful.Robespierre allowed the death of thousands of French persons - men, women and children - during the course of the revolution.He died in 1794, the final victim of the revolution - taken by the guillotine to which he had sent thousands.Robespierre was a lawyer and a politician who was very good at making speeches; at his own trial he delivered a very convincing two hour long speech in his defense. When he was 17, he was chosen out of 500 pupils to deliver a welcome speech to the King (ironically he eventually supported the King's execution later).He was the eldest of four children; his mother died in child birth when he was young and his father, distressed at the loss of his wife, vanished when Robespierre was eight years old, leaving the four children to be cared for by their paternal grandfather and aunts.
When did Edmund halley make his discovery?
He discovered that the comets of 1456, 1531, and 1607 were the same in 1705. In that same year he predicted that that comet would return in 1758. he died in 1742 so he didn't get to see if he was right or not, but the comet in fact did return in 1758.
Who discovered that comets are not just one time vistors to earth?
Edmond Halley. He stated his belief that the comet sightings of 1456, 1531, 1607, and 1682 related to the same comet, which he predicted would return in 1758. When it did it became generally known as Halley's Comet.
What year did Edmund halley discover halley's comet?
Edmund Halley didn't discover the comet, he predicted when it would return. Up to his time no-one had been able to say when a comet would appear. In 1705, using Newtons laws of gravity, he was able to calculate the effects on a comet of the gravity of planets like Jupiter and Saturn; this allowed him to identify comets recorded in 1682, 1607, and 1531 as the same comet. He then calculated it appeared every 76 years and predicted its return in 1758. Halley himself didn't live to see it, but it turned up right on time, was given his name, and has been Halley's comet ever since.
Who predicted next coming of Halley's comet?
Halley's comet was predicted by Edmund Halley he took the comets of 1531-1607-1682, and using Newton law of gravitation (who was Halley good friend) and predicted when that comet would return in 1758 and sure enough on Christmas eve of 1758 it returned. oh and by the way he did not live to see it and also they called him a nut job that whole year Untill its return
Who had a comet named after him?
Astronomer Edmond Halley (1656-1742) mathematically predicted the return of Halley's Comet in1758, and established the periodicity of long-term comets. It was named after Halley in 1759.
Why is halleys commet named halleys commet?
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".
How old is halley?
sometime in April of 2061
What year was Halley's comet found?
It was studied by British astronemer named Edmond Halley.He projected it would come about around 1758-1759, when 1758 came around they saw the comet.And named it after Edmond Halley.So it was offically found in 1758, but of course he studied it way before that.
What did seven century astronomer Edmund halley notice about the comet later named after him?
Halley's Comet is a short-period comet; we can predict that it will return to the inner solar system within our lifetimes, and several times in recent history. Most other comets are either long-period and will not return for centuries, or will never again be visible. Sometimes it is very bright; sometimes it is a "fizzle". It is this element of reassuringly-predictable repeating mystery that makes it noteworthy.
How did Halley's Comet get its name?
Halley's comet got its name from Sir Edmund Halley who, using Newton's laws of motion, predicted that the comet seen in 1531, 1607, and 1682 would return in 1758. Unfortunately, Halley died before seeing the comet return, but when it returned just as he had predicted, the comet was named in his honour by French astronomer Nicolas Louis de Lacaille in 1759.Halley's Comet was named for Edmond Halley, the English astronomer who identified it as a periodic comet.
Who was the finder of Halleys Comet?
The earliest recorded appearance of Halley's Comet was by Chinese astronomers around 239 / 240 BC. It was recorded by astronomers in many cultures, but was not known to be the same comet. Credit for the discovery of Halley's Comet as the same, returning comet, goes to Edmond Halley. Halley had investigated historical records of 24 comets appearing near Earth between 1337 to 1698, and noted similarities in orbits and other parameters between three of them - the ones that were recorded in 1531, 1607 and 1682. In 1705, he published "A Synopsis of the Astronomy of Comets", demonstrating that the comet which appeared to return about every 76 years was likely to be the same comet. Halley predicted its return in 1758, something which he did not live to see, but which was proven to be the case. We cannot know who originally observed the comet that we now call "Halley's Comet". There were documented observations of the comet as early as 240 BCE. Notes from the Talmud indicate that this was a re-appearance of the comet, so people had remembered seeing it before. Halley's Comet is a fairly short-period comet, becoming visible about every 76 years. It got the name "Halley's Comet" because in 1705, Edmund Halley predicted the year that it would re-appear in 1758. He based this on historical observations. The French astronomer Nicolas Louis de Lacaille proposed naming the comet in Halley's honor in 1759.
After whom was halleys comet named?
Haley's comet is a comet that passes around every 76 years, it was last seen in 1986 and will next be seen in 2061. It is the only short-period comet that is visible to the naked eye. It's orbit is highly elliptical and focuses on the sun.Correctly named Halley's comet, this comet was named after Edmond Halley in 1705 and is visible to the naked eye about twice in a person's lifetime.
