15502 Hypeirochus (provisional designation 1999 NV27) is a Jupiter trojan from the Trojan camp, approximately 53 kilometers (33 miles) in diameter. It was discovered on 14 July 1999, by astronomers with the Lincoln Near-Earth Asteroid Research at the Lincoln Lab's ETS near Socorro, New Mexico, in the United States. The dark Jovian asteroid has a rotation period of 15.1 hours and belongs to the 90 largest Jupiter trojans.
Orbit and classification
Hypeirochus is a dark Jovian asteroid in a 1:1 orbital resonance with Jupiter. It is located in the trailering Trojan camp at the Gas Giant's L5 Lagrangian point, 60° behind its orbit (see Trojans in astronomy). It is also a non-family asteroid of the Jovian background population.
It orbits the Sun at a distance of 5.0–5.2 astronomical units (AU) once every 11 years and 7 months (4,238 days; semi-major axis of 5.12 AU). Its orbit has an eccentricity of 0.02 and an inclination of 17° with respect to the ecliptic. The body's observation arc begins with its first observation as 1982 BX14 at Palomar Observatory in January 1982, more than 16 years prior to its official discovery observation at Socorro.

This brief starts where responsible research should: with the source description of “15502 Hypeirochus” as 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 asteroid. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 6, 2026. The linked authority identifier is Q1480782. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1999, 1982 and 2000.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
