185 Eunike
main-belt asteroid
185 Eunike is a dark and very large main-belt asteroid. It was discovered by C. H. F. Peters on March 1, 1878, in Clinton, New York and named after Eunike, a Nereid in Greek mythology whose name means 'happy victory'. The name was chosen to celebrate the Treaty of San Stefano (1878).
This object is orbiting the Sun at a distance of 2.74 AU with an eccentricity of 0.129 and an orbital period of 4.53 years. Its orbital plane is inclined at an angle of 23.2° to the plane of the ecliptic. Using infrared measurements, the diameter has been measured at 160.464 km. It has a primitive carbonaceous composition.
Based upon photometric observations made between 2010 and 2014, this asteroid has a rotation period of 21.812±0.001 hours and a brightness variation of 0.08±0.01 in magnitude. At opposition, the absolute magnitude was measured at 7.45±0.01. It displays a hemispheric albedo dichotomy similar to that on 4 Vesta.
This brief starts where responsible research should: with the source description of “185 Eunike” as main-belt asteroid. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as main-belt asteroid. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q144715. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1878, 2010 and 2014.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
