In classical mythology, a descendant of Hercules; also used in astronomy for a class of asteroids or celestial objects.
From Hercules plus the suffix '-id' (denoting a member of a group or family). In mythology, the Heraclidae (or Herculids) were Hercules's descendants; the astronomical usage is modern.
The Heraclidae in Greek legend supposedly returned to reclaim their ancestor's homeland—this mythological invasion narrative shaped how ancient Greeks understood their own history and migrations!
