When will Halley s Comet be seen again? Please, 3Q

2062 !! Halley's comet is a large comet that has been confirmed to be out of time. In 1705, the famous English astronomer Halley predicted that the comet seen in 1531, 1607 and 1682 would return in 1758 based on Newton's latest laws of motion, and although Halley died in 1742, the comet returned in 1759 as scheduled.

In honor of Halley, people named the comet after him. The average revolution period of the Harley is 76 years, but you can't use 1986 plus a few 76 years to get its exact regression date. The gravitational pull of the main planet causes it to change its cycles, falling into one cycle after another.

Non-gravitational effects (evaporation when close to the Sun) also play an important role in making it change periodically. Between 239 BC and 1986 AD, the orbital cycle varied from year) to year (451 and 1066). Halley's comet's nucleus is approximately 16x8x8 kilometers.

It is almost unique among many comets, large, active, and has a well-defined orbit. This makes it easier to aim at the Giotto Flying Vehicle (ESA-owned). But it doesn't represent what other comets have in common.

Halley's Comet will return to the inner solar system around 2061.

Halley's Comet can be seen every 76 years, until around 2061.

1986 year. Halley's Comet was last seen in 1986. Halley's comet has an orbital period of 76 years, orbiting the Sun in a clockwise direction, and the closer it is to Taixinqiao, the longer Halley's tail becomes.

Halley's Comet was also the first famous great comet to be confirmed by predictions that it would reappear.

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 if it slides or is visible 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 its return 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 mechanisms of comet emitting and tail formation.

2062 !! Halley's Comet will return to the inner solar system around 2061.

Halley's comet is a large comet that has been confirmed to be out of time. In 1705, the famous British astronomer Halley predicted the return of the comet seen in 1531, 1607 and 1682 in 1758 according to Newton's latest laws of motion, and although Halley died in 1742, the comet returned in 1759 as scheduled. In the name of Harley, people named the comet after him.

Halley's Comet has an orbital circumference of 76 79 years, and the next perihelion will be July 28, 2061.

Halley's Comet was the first recorded periodic comet, at least 240 BC, or 466 BC, and there are 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 reappearance 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), there were 29 records, and they were in line with the calculation results.

Halley's Comet originally came to Earth once every 76 years, and the following is the specific time of previous observations... It is estimated that it will come to Earth again in 2062!

History of the Song Dynasty and Astronomical Chronicles": "In March of the third year of Zhiping, he came out of the barracks, saw the east in the morning, six feet long, and the southwest pointed to the dangerous tomb, and gradually traveled east and near.

To Xin has been, see the southwest at night, there are stars in the north without mang, Yi Dongfang, there is no white gas one, three feet wide, through the purple micro pole star and the house, the beginning and the end into the turbidity, Yi Dongxing, Li Wenchang, Beidou Guanwei. To the noon, the stars are full of mang, the length of the zhang is more, the width is more than three feet, the northeast refers to, the calendar is five cars, the white gas is the divergent sky, through the North River, the five princes, Xuanyuan, Taiwei five emperors sit in the five princes and horns, Kang. Clan, Fangsu.

Observation conditions on Earth are harsh.

I believe that as a member of the universe, Halley's Comet also has its own laws of nature. I guess the reason why you are asking is because of eighth-grade physics, so let me tell you.

Thank you for your support and hope my answers can help you.

Halley's Comet has a cycle of 76 years. The last time we visited Earth was in 1986 and the next time we visited it was in 2062.
