    3367 Alex, provisional designation 1983 CA3, is a metallic asteroid from the outer region of the asteroid belt, about 17 kilometers in diameter. It was discovered by American astronomer Norman Thomas at Lowell's Anderson Mesa Station, near Flagstaff, Arizona, on 15 February 1983.[8]

    The X-type asteroid orbits the Sun at a distance of 2.6–3.0 AU once every 4 years and 8 months (1,699 days). Its orbit shows an eccentricity of 0.07 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 9.6 hours[7] and an albedo between 0.10 and 0.30, according to the surveys carried out by the Japanese Akari satellite and the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission.[4][5][6] However, the Collaborative Asteroid Lightcurve Link (CALL) assumes a much lower albedo of 0.06, which would be typical value for a P-type rather than a M-type asteroid, known to have intermediate albedos above 0.10.[3]

    The minor planet was named by the discoverer in honor of his grandson, Alex R. Baltutis.[2]
