Once every 76 years, is Halley's Comet the Comet with the highest frequency of return?

There are countless celestial bodies in the vast universe, and the most beautiful celestial body is a comet. Comets are called "broom stars" in our slang. So far, more than 1600 comets have been discovered, but the number of comets that can be seen with the naked eye is quite small. Even if you look at them through a telescope, they are only about 20. Comets are strange. They are large in size, but relatively small in mass.

Halley's Comet

Halley's Comet was named after edmund halley, a British physicist who measured its orbital data for the first time and successfully predicted the return time. Note that Halley's comet was not discovered for the first time. In 240 BC or 466 BC, Halley's Comet was recorded in some countries, including China. However, people didn't know at that time that it was the same comet. China's record of Halley's Comet can be traced back to Shang Dynasty, when people mainly recorded the arrival of Halley's Comet.

The orbital period of Halley's comet is between 76 and 79 years, and it orbits the sun once every 76. 1 year. The next perihelion is in late July of 206 1. Halley's comet is the only short-period comet that can be seen directly from the earth with the naked eye, and it is also the only comet that can be seen twice with the naked eye in human life. Other comets visible to the naked eye may be more spectacular and beautiful, but many comets orbit the sun for a very long period, some even reaching thousands of years.

Halley's comet has a very low surface temperature and is a cold celestial body in the solar system. When it is close enough to the sun, there will be beautiful Hui hair that we can see with the naked eye. It is a thin, fuzzy and transient atmosphere, and there will be a tail, that is, the long tail. Why are there hui fa hui Wei? Because comets are ice cores, the closer they are to the sun, the more they melt. The closer to the sun, the greater the heat and the faster the melting speed. In addition, under the action of the solar wind, the longer the tail, the tail always turns its back on the sun.

Do you know that?/You know what? Do you know that?/You know what? Every time Halley's Comet comes, something strange will appear on the earth. For example, hens will lay Halley's comet eggs, and the eggs will be covered with stars. 1682, when Comet Halley visited the earth periodically, a hen laid an unusual egg in Marburg, Germany, and the shell was covered with stars. 1758, a hen in a village near Heuck, England, laid an egg with a comet pattern clearly painted on the eggshell. Isn't it incredible and interesting? This century is 206 1, so let's look forward to the coming of Halley's comet again!
