A list of constellations that are no longer recognized by the star’s governing body, the International Astronomical Union. They sound to me like the attendance list from a 2009 kindergarten class: Maenalus, Malus, Apis, Cerberus…

Definitely check out the most obsolete of the constellations:  Officina Typographica, a “constellation that was made in order to honor one of the machines used to create scientific advancements, the printing press. Officina Typographica appeared on a least one other star atlas, but was quickly forgotten by astronomers.” It appears to be in the shape of an old printer’s type tray.
