4349 Tibúrcio
asteroid
4349 Tibúrcio, provisional designation 1989 LX, is a dark asteroid from the central region of the asteroid belt, approximately 29 kilometers in diameter. It was discovered on 5 June 1989, by German astronomer Werner Landgraf at ESO's La Silla Observatory in northern Chile.
With 53.5°, it had been the asteroid with the smallest angular distance from the Sun ever discovered. It was later named after Brazilian amateur astronomer Júlio Tibúrcio.
Orbit and classification
Tibúrcio orbits the Sun in the central main-belt at a distance of 2.0–3.3 AU once every 4 years and 3 months (1,550 days). Its orbit has an eccentricity of 0.24 and an inclination of 11° with respect to the ecliptic.
One day before its first identification as 1931 AE, a precovery was taken at Lowell Observatory in 1931, extending the body's observation arc by 58 years prior to its official discovery at La Silla.
Physical characteristics
The asteroid has been characterized as an X-type asteroid by Pan-STARRS' large-scale photometric survey.
Rotation period
A rotational lightcurve of Tibúrcio was obtained from photometric observations by astronomer David Higgins at the Australian Hunters Hill Observatory (E14) in October 2010. Lightcurve analysis gave a well-defined rotation period of 16.284 hours with a brightness variation of 0.40 magnitude (U=3).
Begin with the source’s own compact description: “4349 Tibúrcio” is asteroid. The dossier treats that line as a proposition to test through Tibúrcio and asteroid, not as a finished interpretation.
Why this record matters
The phrase “asteroid” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 6, 2026. The linked authority identifier is Q153705. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1989, 1931 and 2010.
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.
