(5150) Fellini is an asteroid of the main inner belt that was discovered on October 17, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory . Unconfirmed sightings of the asteroid had already been made in March 1939 (1939 EK) at the Iso-Heikkilä Observatory ( Finnish : Iso-Heikkilän tahtitorni ) of the University of Turku .
The mean diameter of the asteroid was calculated to be 5.401 km (± 0.229). The albedo of 0.419 (± 0.098) indicates a light surface.
Mean solar distance ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid correspond to the Vesta family , a large group of asteroids named after (4) Vesta , the second largest asteroid and third largest celestial body in the main belt. Studies have shown that (5150) Fellini broke away from the actual Vesta family around 1.4 billion years ago. The rotation period was established in 2015 by Dagmara Oszkiewicz et al. with 5.1953 h (± 0.0002) and is clockwise.
(5150) Fellini was born on February 26, 1994 at the suggestion of M.-R. Visscher named after the Italian filmmaker Federico Fellini .
