1513 Mátra, provisional designation 1940 EB, is an asteroid from the inner regions of the asteroid belt, about 6 kilometers in diameter. It was discovered by Hungarian astronomer György Kulin at Konkoly Observatory on 10 March 1940.[6]
The asteroid is a member of the Flora family, a large group of rocky S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 2.0–2.4 AU once every 3 years and 3 months (1,186 days). Its orbit shows an eccentricity of 0.10 and is tilted by 4 degrees to the plane of the ecliptic. It has a somewhat longer than usual rotation period of 24 hours[5] and an albedo of 0.19, according to the space-based Wide-field Infrared Survey Explorer and its subsequent NEOWISE mission.[4] The Collaborative Asteroid Lightcurve Link assumes a slightly higher albedo of 0.24, a figure in line with those typically found for Flora asteroids.[3]
The minor planet was named after the Mátra mountain range in northern Hungary, where the outstation of the discovering Konkoly Observatory is located.[2]
