5185 Alerossi, provisional designation 1990 RV2, is an asteroid from the middle region of the asteroid belt, about 13 kilometers in diameter. It was discovered by American astronomer Henry Holt at the U.S. Palomar Observatory, California, on 15 September 1990.[4]

The asteroid orbits the Sun at a distance of 2.5–2.9 AU once every 4 years and 5 months (1,599 days). Its orbit shows an eccentricity of 0.08 and is tilted by 8 degrees to the plane of the ecliptic. It has an albedo of 0.14, according to two observations carried out by the Infrared Astronomical Satellite, IRAS.[3]

The minor planet was named in honor of Italian geodesists Alessandro Rossi (b. 1964), member of the Group of Satellite Flight Dynamics at the Istituto CNECE in Pisa, Italy. Expert in space geodesy and participant in the Laser Geodynamics Satellites (LAGEOS) mission, he also studies artificial orbital debris that pollute the near-Earth environment. In addition, Rossi studied natural debris around space mission targets to optimize encounter and rendezvous operations. He has also studied the hazard of Earth-crossing objects.[2]
