In fact, the origin of the name of Halley's comet is similar to the names of many planets discovered by human beings at present, and they are all named after the scientists who discovered it and defined it. The reason for doing this is also very simple, that is, to commemorate the contribution made by this scientist. Halley's Comet was discovered by edmund halley. At the beginning, Harley's fame was largely due to his article "South Star List", which was published by Harley in the southern hemisphere and the first article about the southern hemisphere. At that time, Harley established the first serious observatory in the southern hemisphere.

1682, when Harley was observing in the southern hemisphere, he suddenly found a strange monster with a long tail in the sky. This is what we call a comet in astronomy. Harley collected and integrated a lot of historical data about comets. After calculation and research, it was found that the comets in 1862 and the two comets in 153 1 and 1607 had very close orbits. After discovering this rule, Harley began to collect earlier historical records about comets, and found that a bright comet appeared in this orbit every 75 or 76 years. 1720, Harley officially announced his discovery to people, and predicted that such a comet would come to people on1758+Christmas on February 25th. 1758, at this time, Harley has left this world 16 years, but mankind has not forgotten his predictions. Sure enough, this day, people once again saw a bright comet running in this orbit. Later, in memory of Halley, people named this comet Halley's Comet. The last return of Halley's comet was in 1986. If converted in 75 years, we may have a chance to see it again when the comet returns in 206 1 year.
