198 Ampella
main-belt asteroid
198 Ampella is a Main belt asteroid that was discovered by Alphonse Borrelly on June 13, 1879. The name seems to be the feminine form of Ampelos, a satyr and good friend of Dionysus in Greek mythology. It could also derive from the Ampelose (plural of Ampelos), a variety of hamadryad. It is an S-type asteroid.
So far Ampella has been observed occulting a star once, on November 8, 1991, from New South Wales, Australia.
This asteroid has been resolved by the W. M. Keck Observatory, resulting in a size estimate of 53 km. It is oblate in shape, with a size ratio of 1.22 between the major and minor axes. Measurements from the IRAS observatory gave a similar size estimate of 57 km. Photometric measurements made in 1993 give a rotation period of 10.38 hours.
“198 Ampella” enters the record as main-belt asteroid. Crown Archives preserves that source wording while asking what Ampella, main-belt and asteroid can confirm, complicate or overturn.
Why this record matters
“198 Ampella” is worth following because a concise public description often conceals a longer documentary argument. Here, Ampella, 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 Q146513. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1879, 1991 and 1993.
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.
