How does the astronomical definition of Crater differ from its geological counterpart?

Answer

The astronomical object is a grouping of stars, while the geological one refers to an impact scar or volcanic vent.

The confusion arises because the geological term 'crater' describes a bowl-shaped depression on planetary surfaces, while the constellation Crater is a formal classification of stars defined by the IAU.
