9905 Tiziano, provisional designation 4611 P-L, is an asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 24 September 1960, by Dutch astronomer couple Ingrid and Cornelis van Houten, as well as Dutch–American astronomer Tom Gehrels. The asteroid was spotted during the Palomar–Leiden survey by examining photographic plates taken at Palomar Observatory, California, United States.[3]

Orbit of Tiziano (blue), with the inner planets and Jupiter (red)

Tiziano orbits the Sun at a distance of 2.1–2.7 AU once every 3 years and 9 months (1,361 days). Its orbit has an eccentricity of 0.13 and an inclination of 13° with respect to the ecliptic.[1] As no precoveries were taken, and no prior identifications were made, the body's observation arc begins with its official discovery observation at Palomar.[3]

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Tiziano measures 5.239 kilometers in diameter and its surface has an albedo of 0.099.[4] It has an absolute magnitude of 14.4[1] As of 2017, the asteroid's rotation period and shape remain unknown.[5]

The survey designation "P-L" stands for Palomar–Leiden, named after Palomar Observatory and Leiden Observatory, which collaborated on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory where astrometry was carried out. The trio are credited with the discovery of several thousand minor planets.[6]

This minor planet was named after Tiziano Vecellio (c. 1488–1576) known in English as Titian, who was an Italian Renaissance painter and the most important member of the Venetian school. His application and use of color, would exercise a profound influence not only on painters of the Italian Renaissance, but on future generations of Western art. Titian is famous for the Equestrian Portrait of Charles V and for the Portrait of Pope Paul III.[2] Naming citation was published on 2 April 1999 (M.P.C. 34356).[7]
