Astronomical circles began to understand and study the Leonid meteor shower. Newton proved in 1864 that the Leonid meteor shower has been recorded since 902. There are ten years in all, six of which are taken from China's official history books.

Leonid meteor shower reappeared in1866165438+10, and its trajectory was calculated. 1867165438+1October Hautpoul gives the orbit of comet 1866 I, which is called the mother comet of the meteor swarm because it is very similar to the orbit of the Leonid meteor swarm. 1899 No Leonid meteor shower was observed, and neither were comets. Some people think that this comet has disintegrated. The public was very angry at being cheated, and their distrust of astronomers suddenly increased.
