145 Adeona
main-belt asteroid
145 Adeona is a large asteroid from the intermediate asteroid belt, approximately 150 kilometers (93 miles) in diameter. Its surface is very dark, and, based upon its classification as a C-type asteroid, is probably composed of primitive carbonaceous material. The spectra of the asteroid displays evidence of aqueous alteration. The Adeona family of asteroids is named after it.
It was discovered by C. H. F. Peters on June 3, 1875, from the observatory at Hamilton College, Clinton, New York. Peters named it after Adeona, the Roman goddess of homecoming, because he had recently returned from a journey across the world to observe the transit of Venus. Peters also discovered 144 Vibilia on the same night.
During 2001, Adeona was observed by radar from the Arecibo Observatory. The returned signal matched an effective diameter of 151 ± 18 km. This is consistent with the asteroid dimensions computed through other means.
“145 Adeona” enters the record as main-belt asteroid. Crown Archives preserves that source wording while asking what Adeona, main-belt and asteroid can confirm, complicate or overturn.
Why this record matters
“145 Adeona” is worth following because a concise public description often conceals a longer documentary argument. Here, Adeona, main-belt and asteroid 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 Q139313. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1875 and 2001.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
