108 Hecuba

Hecuba (minor planet designation: 108 Hecuba) is a fairly large and bright main-belt asteroid. 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. It became the first asteroid discovered to orbit near a 2:1 mean-motion resonance with the planet Jupiter,[8] and is the namesake of the Hecuba group of asteroids.[9]

In the Tholen classification system, it is categorized as a stony S-type asteroid,[10] while the Bus asteroid taxonomy system lists it as an Sw asteroid.[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.[citation needed]
