The sky is not divided up equally between the constellations. Pyxis takes up 220.833 sq. degrees of the night sky which equates to 0.54% of the night sky. The constellation gets its name as it name means The Compass . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by Abbé Nicolas Louis de Lacaille years later.

Pyxis is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Pyxis is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere.

The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.

List of Named Stars in Pyxis without Extrasolar Planets

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
