Felis (constellation)

Former constellation Felis Felis (Latin for cat) was a constellation created by French astronomer Jérôme Lalande in 1799. He chose the name partly because, as a cat lover, he felt sorry that there was not yet a cat among the constellations (although there are two lions and a lynx). It was between the constellations of Antlia and Hydra. This constellation was first depicted in the Uranographia sive Astrorum Descriptio (1801) of Johann Elert Bode. It is now obsolete.[1] Its brightest ...
