At the beginning of 1758, messier of the French Observatory began to observe, hoping to be the first person to confirm the return of comets. 1759 65438+1October 2 1, and he finally found the comet. Unfortunately, the glory of observing the return of the comet for the first time does not belong to him. It turned out that a farmer astronomy enthusiast near Dresden, Germany, first arrived there on Christmas Eve of 1758 and found the returning comet.
1March 759, Halley's comet passed the perihelion in1March 4, just one month earlier than Craehot's prediction. At this point, Harley has been buried underground for more than ten years. The life of scientists is limited, but their contribution to science will be eternal. As Halley wished, everyone did not forget Halley and named this comet Halley's Comet.
The observation and study of Halley's comet not only confirmed the existence of periodic comets, but also greatly promoted the development of comet astronomy. In addition, Comet Halley, like a visiting ambassador, regularly reviews the planets in the solar system, experiences various environments and brings back rich information. Therefore, every time it returns, it will arouse great interest of astronomers.
Comet Halley returns once every 76 years, and most of the time it lives in the marginal area of the solar system, even with the largest telescope in modern times, it is difficult to find it. People on earth can only see it within three or four months of its return. Generally speaking, people's life span is only about 70 years old, so it is rare for a person to see Halley's comet twice. Only some "longevity stars" have this opportunity. The first time I saw it, I babbled at a young age, and the second time I saw it, I was old.
What needs to be explained to readers here is that messier didn't become the first person to confirm the return of the comet, but he didn't lose heart. Instead, he began to search for comets systematically, observing them year after year in the morning and after dusk. He discovered 2 1 comet in his life, and the number of comets observed reached 46. On one occasion, King Louis XV of France joked that he was a "comet detective". Although this is a joke, it is the highest praise for messier's life-long search for comets.
