108 Hecuba
outer main-belt asteroid
108 Hecuba is a fairly large and bright main-belt asteroid. It was discovered by Karl Theodor Robert Luther on 2 April 1869, 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, and is the namesake of the Hecuba group of asteroids.
In the Tholen classification system, it is categorized as a stony S-type asteroid, while the Bus asteroid taxonomy system lists it as an Sw asteroid. 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.
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.
“108 Hecuba” enters the record as outer main-belt asteroid. Crown Archives preserves that source wording while asking what Hecuba, outer and main-belt can confirm, complicate or overturn.
Why this record matters
“108 Hecuba” is worth following because a concise public description often conceals a longer documentary argument. Here, Hecuba, outer and main-belt provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q132948. VIAF identifies the subject as 235081912. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1869 and 2007.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
