It was discovered by Karl Theodor Robert Luther on 2 April 1869,[7] and named after Hecuba, wife of King Priam in the legends of the Trojan War in Greek Mythology.

This object is orbiting the Sun with a period of 5.83 years and an eccentricity of 0.06.

[11] Observations performed at the Palmer Divide Observatory in Colorado Springs, Colorado in during 2007 produced a light curve with a period of 17.859 ± 0.005 hours with a brightness variation of 0.11 ± 0.02 in magnitude.

[12] 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.
