3752 Camillo is an Apollo asteroid with a perihelion (closest approach to the Sun) of 0.99 AU and an orbital period of 614 days (1.68 years).[1] It has a well determined orbit with an observation arc of almost 40 years and an uncertainty parameter of 0.[1]
The asteroid was discovered on August 15, 1985 by Eleanor F. Helin and Maria A. Barucci using a 0.9-metre (35 in) telescope.[2] Lightcurve studies by Pravec in 1998 suggest Camillo has an elongated shape with a diameter of about 2.3 km and takes 38 hours to rotate.[2]
The closest point between the orbit of the Earth and the orbit of Camillo (Earth MOID) is currently 0.07955 AU (11,901,000 km; 7,395,000 mi)[1] so Camillo does not come close enough to Earth to qualify as a potentially hazardous asteroid. Camillo came to perihelion on 1976-Jan-06 and on 1976-Feb-17 Camillo passed 0.08013 AU (11,987,000 km; 7,449,000 mi) from Earth.[1]
2013 passage
Camillo came to perihelion on 27 December 2012.[1] On 12 February 2013 the asteroid passed 0.14775 AU (22,103,000 km; 13,734,000 mi) from Earth[1] and had an apparent magnitude of 13.[2] During the 2013 passage the asteroid was studied by radar using Goldstone and Arecibo.[2]
