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). It has a well determined orbit with an observation arc of almost 40 years and an uncertainty parameter of 0.
The asteroid was discovered on August 15, 1985 by Eleanor F. Helin and Maria A. Barucci using a 0.9-metre (35 in) telescope. 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.
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) 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.
2013 passage
Camillo came to perihelion on 27 December 2012. On 12 February 2013 the asteroid passed 0.14775 AU (22,103,000 km; 13,734,000 mi) from Earth and had an apparent magnitude of 13. During the 2013 passage the asteroid was studied by radar using Goldstone and Arecibo.
