Which comet is the most famous comet in history?
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.
Halley's Comet has an extremely elliptical orbit around the Sun with an eccentricity of 0.967. Its average orbital radius is 17.8 AU and it was last observed in 1986. When will Halley's Comet appear n?
Halley's Comet has an orbital period of approximately 76 years. Since it was last observed in 1986, it is expected to return to the inner solar system and be visible again around 2061.
When is halleys comet coming again?
It can be seen every 75-76 years. The next predicted perihelion of Halley's Comet will be 28 July 2061.
What year did the first comet pass over the US?
Comets have been passing through the solar system since historical times. But no comet could have 'passed over' the US before 1776
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.

How did they observe halley comet since 1682?
he watched the comet every 75 years

What was the first comet to be visited by a spacecraft?
The comet now known as Halley's Comet has been observed since at least 240 BCE, but it was not known to be something that reappeared periodically. It wasn't until 1705 that English astronomer Edmond Halley determined that it was the same comet that appeared periodically.
Why did people think Haleys Comet would end the world?
Probably because they were uninformed. Science has come a long way since then and we know Haleys Comet will probably never collide with Earth and end all life.
Is the ion tail of a comet on the top or bottom?
It is on the side of the comet furthermost from the Sun. Conventional wisdom dictates gravity defines up and down therefore it is on "top" of the comet since the comet is trapped by the gravity of the Sun.
If Edmond Halley didn't discover Halley's Comet then who did?
Halley's Comet had been seen every 76 years since at least 240 BC, and probably earlier than that. But most people didn't live 76 years, and the written records weren't exactly common back then. So few people noticed that there was a comet coming by every 76 years. Edmund Halley DID make the connection, and analyzed the data of comet appearances in 1531, 1607 and 1682. In 1705, Halley said that these were all the SAME comet, and that the comet would return in 1758. It did (just barely!) and was named Halley's Comet in his honor.
When was the last time halley appeared?
Edmund Halley himself has not been seen since he was buried in the graveyard of the old church of St. Margaret, Lee, England. The comet that bears his name, Halley's Comet, was last seen by the public in 1986. However, the comet was on the far side of the Sun, and very few people were able to see it at all. Halley's Comet was last seen through the Very Large Telescope array at Paranal, Chile, in 2003. Halley's Comet will next appear in 2061, when it should be much more visible than it was in 1986, and the 2134 pass is expected to be VERY close to Earth. Too bad we won't be around to see it!
How old is Halley's comet?
Halley's Comet, if it is a typical comet, was created during or shortly after the formation of the solar system, some 4.6 billion years ago. Although it may have originally had a very elliptical (long-period) orbit, the current (short-period) orbit may have been established between 10,000 and 200,000 years ago. It has been observed from Earth since about 240 BC (about 2250 years) and last appeared in the inner solar system in February, 1986.
