Template:Short description Template:Infobox planet
108 Hecuba is a fairly large and bright main-belt asteroid. It was discovered by Karl Theodor Robert Luther on 2 April 1869,<ref name="IAU_MPC"/> 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. It became the first asteroid discovered to orbit near a 2:1 mean-motion resonance with the planet Jupiter,<ref name="Broz2005"/> and is the namesake of the Hecuba group of asteroids.<ref name="McDonald1948"/>
In the Tholen classification system, it is categorized as a stony S-type asteroid,<ref name=Blanco1994/> while the Bus asteroid taxonomy system lists it as an Sw asteroid.<ref name="DeMeo2009"/> 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.<ref name="Warner2007"/>
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.Template:Citation needed
