    1299 Mertona, provisional designation 1934 BA, is an assumed carbonaceous asteroid from the outer region of the asteroid belt, about 15 kilometers in diameter. It was discovered on 18 January 1934 by French astronomer Guy Reiss at the North African Algiers Observatory in Algeria.[11]

    The asteroid orbits the Sun at a distance of 2.3–3.3 AU once every 4 years and 8 months (1,711 days). Its orbit shows an eccentricity of 0.19 and is tilted by 8 degrees to the plane of the ecliptic. It has a well-defined rotation period of 4.98 hours.[6][7][8][9] While observations by the space-based Akari and Wide-field Infrared Survey Explorer gave a geometric albedo of 0.22 and 0.23, respectively, the Collaborative Asteroid Lightcurve Link (CALL) assumes the body to be a darker, carbonaceous C-type asteroid with an albedo of only 0.06.[4][5] Based on this assumption, the body's calculated diameter would be much larger, about 28 kilometers.[3]

    The asteroid was named after English astronomer Gerald Merton (1893–1983),[2] who was president of the British Astronomical Association between 1950 and 1952.[12]
