37432 Piszkéstető, provisional designation 2002 AE11, is an asteroid from the inner regions of the asteroid belt, roughly 3 kilometers in diameter. It was discovered by the Hungarian astronomers Krisztián Sárneczky and Zsuzsanna Heiner at the Konkoly Observatory's Piszkéstető Station northeast of Budapest, Hungary, on 11 January 2002.[2]
The asteroid orbits the Sun at a distance of 2.0–2.8 AU once every 3 years and 8 months (1,342 days). Its orbit shows an eccentricity of 0.17 and is tilted by 5 degrees to the plane of the ecliptic. Little is known about the asteroids effective size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty – i.e. a condition code of 0 – and an observation arc that spans over a period of more than two decades due to precovery images already taken in 1995.[1]
Based on its absolute magnitude of 15.6, its diameter could be anywhere between 2 and 5 kilometers, assuming an albedo in the range of 0.05 to 0.25.[3] Since asteroids in the inner main-belt are often of a silicaceous rather than of a carbonaceous composition, with higher albedos, typically around 0.20, the asteroid's diameter might be on the lower end of NASA's published conversion table, as the higher the reflectivity (albedo), the smaller the body's diameter for a given absolute magnitude (brightness).[3]
The asteroid is named in honour of the discovering observatory, the Piszkéstető Station, located in the Mátra Mountains, about 80 kilometers northeast of Hungary's capital. The station belongs to the Konkoly Observatory in Budapest.[2]
