Felis is a now obsolete constellation in the northern hemisphere, created in
1799 by Jérôme Lalande.
Between 1791 and 1801, French astronomer Jérôme Lefrançois de Lalande
put together a star catalogue containing 47,390 stars. As part of it, he designed
four new constellations.
I am very fond of cats. I will let this figure scratch on the chart. The starry sky has worried me quite enough in my life, so that now I can have my
joke with it.
According to R.H. Allen, these were the words with which
Lalande introduced the fourth of his creations, Felis, the cat.
Lalande selected five faint stars in the southern part of the constellation Hydra with
156 G. Hydrae in the center.
Considering Lalande's quote above, he was probably not too serious about this constellation so it wasn't surprising that Felis didn't make the cut
when the IAU decided on its
88 official constellations.
However, 90 years later, the IAU's Working Group on Star Names returned a remnant of
Lalande's constellation: In 2018, Felis' brightest star, HD 85951 was named Felis.
On October 18, 1963, the cat returned to the stars in a special way. A French Véronique sounding rocket
reached an altitude of 96 miles. On board was Félicette, the first cat in space.
