    2997 Cabrera, provisional designation 1974 MJ, is an asteroid from the central regions of the asteroid belt, approximately 8 kilometers in diameter.

    It was discovered by the Felix Aguilar Observatory at Leoncito Astronomical Complex, Argentina, on 17 June 1974. It orbits the Sun in the central main-belt at a distance of 2.0–3.1  AU once every 4 years and 1 month (1,492 days). Its orbit has an eccentricity of 0.20 and an inclination of 7° with respect to the ecliptic. [1]

    It is named after Argentine astronomer Ascención Cabrera (1917–2003), long on the staff of the La Plata Observatory and collaborator at the Argentine National Observatory. [2]
