(5368) Vitagliano is an asteroid of the outer main asteroid belt , which was discovered on September 21, 1984 by Henri Debehogne at the La Silla Observatory at a magnitude of 18 mag. Subsequently, the asteroid could already be detected on recordings of the Lowell Observatory from February 11, 1980 and the Siding Spring Observatory from 1983.
The asteroid is a member of the Hilda group , so it is in a 3: 2 orbit resonance with the planet Jupiter . Although according to the currently known orbital elements the minimum distance between the orbits (MOID) of (5368) Vitagliano and Jupiter is only about 0.71 AU (107 million km), the asteroid and planet will approach the present one within a period of 100,000 years Due to their mutual orbit resonance, the epoch is never less than about 1.69 AU (253 million km).
The asteroid's period of rotation was studied by Brian D. Warner , Robert D. Stephens, and Daniel R. Coley at the Center for Solar System Studies in Rancho Cucamonga , California, in September and October 2016. The light curve gave a rotation period of 59.36 ± 0.04 hours. In previous observations at various observatories, the light curve had not yet been sufficient for a reliable determination.
The asteroid was named on July 21, 2005 after the Italian professor Aldo Vitagliano , who teaches general and inorganic chemistry at the Federico II University in Naples . Vitagliano developed the "SOLEX" celestial mechanics program, with which the ephemeris of the bodies of the solar system, including asteroids and comets, can be calculated with high accuracy and over long periods of time. The name was given after a suggestion by Jean Meeus .
