The abolished constellation

Cat constellation is an abandoned constellation, which was founded by French astronomer Lalander in 1799. The main reason why Lalander created this constellation is that he likes cats very much, but he can't see the constellation symbolizing cats in the starry sky, so he set up a cat constellation to make up for his regret.

Finally, other scientists and astronomers thought that this constellation was unnecessary at all, and then it automatically disappeared from the modern star map.
