“3268 De Sanctis”的意思、由来-开放百科全书

The asteroid orbits the Sun in the inner main-belt at a distance of 2.0–2.6 AU once every 3 years and 7 months (1,313 days; semi-major axis of 2.35 AU). Its orbit has an eccentricity of 0.13 and an inclination of 6° with respect to the ecliptic.

The body's observation arc begins with a precovery taken at Palomar Observatory in December 1951, nearly three decades prior to its official discovery observation La Silla.^[1]

Physical characteristics

Rotation period

A first rotational lightcurve of De Sanctis was obtained from photometric observations by Polish astronomer Wiesław Wiśniewski at the University of Arizona. Lightcurve analysis gave a rotation period of 17 hours with a brightness amplitude of 0.4 magnitude ({{small|U=2}}).^[9]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, De Sanctis measures 6.033 kilometers in diameter and its surface has an albedo of 0.228,^[7]^[8] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the parent body of the Flora family – and derives a diameter of 5.88 kilometers based on an absolute magnitude of 13.32.^[3]

Naming

This minor planet was named by the first discoverer after the second, Giovanni de Sanctis (born 1949), an Italian astronomer at the Observatory of Turin, who closely collaborated with Henri Debehogne at the European Southern Observatory in La Silla, Chile, during the early 1980s. The official naming citation was published by the Minor Planet Center on 22 June 1986 ({{small|M.P.C. 10849}}).^[32]
