1582 Martir
asteroid
1582 Martir, provisional designation 1950 LY, is a carbonaceous background asteroid from the outer regions of the asteroid belt, approximately 37 kilometers in diameter. It was discovered on 15 June 1950, by Argentine astronomer Miguel Itzigsohn at the La Plata Astronomical Observatory in Argentina. The asteroid was named after the First Lady of Argentina, Eva Perón.
Orbit and classification
Martir is a background asteroid that does not belong to any known asteroid family. It orbits the Sun in the outer main-belt at a distance of 2.8–3.6 AU once every 5 years and 7 months (2,047 days). Its orbit has an eccentricity of 0.13 and an inclination of 12° with respect to the ecliptic. The body's observation arc begins at the discovering observatory with its official discovery observation.
Physical characteristics
Martir has been characterized as a carbonaceous C-type asteroid by PanSTARRS photometric survey.
Rotation period
In May 2000, a rotational lightcurve of Martir was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory (716) in Colorado. After a review of the previous lightcurve analysis, a half-period solution with a fit on a monomodal lightcurve gave a revised rotation period of 9.84 hours with a brightness amplitude of 0.31 magnitude (U=2).

Why this record matters
“1582 Martir” is worth following because a concise public description often conceals a longer documentary argument. Here, Martir 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 5, 2026. The linked authority identifier is Q141085. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1582, 1950 and 2000.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
