What is the average period of Halley s Comet

Halley's Comet has an average period of years and orbits the Sun.

Halley's Comet is named after the English physicist Edmund Halley (1656-1742) who first measured his orbital data and successfully predicted the time of return. Halley's Comet was the first recorded periodic comet, at least 240 BC, or 466 BC, and there were clear records of its occurrence in China, ancient Babylon, and medieval Europe, but it was not known at the time that it was a recurrence of the same comet. According to Zhu Wenxin's research:

From the seventh year of Qin Shi Huang (240 BC) to the second year of Xuantong of the Qing Dynasty (1910), a total of 29 records were recorded, and the calculation results were in line with the results. Halley's Comet has an orbital period of 76 79 years, and its next perihelion is July 28, 2061.

In ancient times, people thought that the appearance of comets was a bad omen, until the 17th century, when the English astronomer Halley began to calculate the orbits of comets, he found that the comets that appeared in 1682, 1607 and 1531 had similar orbits, he judged that the three comets were actually the same comet, and predicted that it would appear again at the end of 1758 or early 1759. In 1759, the comet appeared. Although Halley had died in 1742, the comet was called "Halley's Comet" in his honor.

Halley's comet has a return period of 76 years, with the most recent return in 1986.

Halley's Comet has a return period of 76 years. The most recent return was in 1986 and the next one is in 2062.

It takes 76 years for Halley's Comet to move around in its elliptical orbit.

76 years, if you are lucky, you can meet it in your lifetime.

Once or twice!

I don't think I had a chance to watch it... Alas, life is like a play.

If I meet Harley again, I'll be an octogenarian. ^_

Year.

Expand your knowledge: Thunder Comets are periodic comets that orbit the Sun once a year and can be seen with the eyes of the Flesh Burning Hall. It was named after the British physicist Edmund Halley, who was the first to determine his orbital data and successfully predicted the time of regression.

Halley's Comet has an orbital period of 76 79 years, and its next perihelion will be on July 28, 2061. Halley's Comet has an orbital period of 76-79 years.

Halley's Comet was the first recorded periodic comet, and at the latest in 240 BC or 466 BC, there were clear records of the comet's appearance in China, ancient Babylon, and medieval Europe, but it was not known at the time that it was a recurrence of the same comet.

Halley's Comet is the only short-period comet that can be seen directly from Earth with the naked eye, and the only comet that can be seen twice in a lifetime with the naked eye. Other comets that can be seen with the naked eye may be more spectacular and beautiful, but those are comets that only appear once in thousands of years.

Halley's Comet last returned in 1986, and the next return will be in mid-2061. At the time of the return of the Comet in 1986, Halley's Comet became the first comet to be observed in detail by a spacecraft, providing first-hand information on the structure of the comet's nucleus and the mechanism of comet emitting and tail formation.

Halley's Comet was the first comet to be predicted to return by the famous British astronomer Halley. In 1682, while Professor of Mathematics and Physics at Oxford, Halley observed a large comet and devoted himself to the study of the comet's orbit.

He used Newton's law of gravitation to calculate the orbits of 24 comets observed from 1337 to 1682, and found that only the one that appeared in 1682 had an elliptical orbit.

1. Halley's Comet appears about once in about 76-79 years.

2. The temperature on the surface of Halley's Comet is very low, this is a rather cold celestial body, if it is very close to the sun, people can see beautiful hair, and the tail of the comet is also more common. Comets are ice-cored, and as long as they are close to the sun, they will easily melt away, and the closer they get to the sun, the more they will melt, and the tail of the comet will become longer under the action of the solar wind.

3. Halley's Comet is currently the most famous comet, in fact, it was recorded as early as 240 BC, but everyone does not know that it is the same comet. Originally, people thought that comets were bad omens, and they used comets to tell fortunes, etc., and they also called comets broom stars, and comets were called broom stars.
