Former constellations

Former constellations are constellations that are no longer recognized by the International Astronomical Union for various reasons. Many of these constellations were recognized by authorities for long periods of time, even centuries in many cases, which means they have historical value and can be found on older star charts.

Argo Navis

Argo Navis is the only constellation from Ptolemy's original list of 48 constellations that is no longer officially recognized. Due to its large size, it was split into three constellations by Nicolas Louis de Lacaille: Carina (the keel), Puppis (the poop deck), and Vela (the sails). This new version was introduced in the star catalog Coelum Australe Stelliferum in 1763, which was published after de Lacaille's death.

Quadrans Muralis

Quadrans Muralis was originally created in 1795, being placed in the northern skies between the now modern accepted constellations Boötes and Draco. The Quadrantids meteor shower is still named after this former constellation.

Remnant nomenclature

  • 53 Eridani retains the name Sceptrum from the former constellation Sceptrum Brandenburgicum.
