108 Hecuba is a fairly large and bright main-belt asteroid.
Hecuba orbits within the Hygiea family of asteroids but is not otherwise related to other family members because it has a silicate composition; Hygieas are dark C-type asteroids.
Hecuba was discovered by R. Luther on April 2, 1869, and named after Hecuba, wife of King Priam in the legends of the Trojan War in Greek Mythology.
