95179 Berkó, provisional designation 2002 BO, is an asteroid from the inner regions of the asteroid belt, roughly 2 kilometers in diameter. It was discovered on 16 January 2002, by the Hungarian astronomers Krisztián Sárneczky and Zsuzsanna Heiner at the Konkoly Observatory's Piszkéstető Station northeast of Budapest, Hungary.[4]
The asteroid has 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 15 years. It orbits the Sun at a distance of 1.9–2.9 AU once every 3 years and 9 months (1,354 days). The orbit shows an eccentricity of 0.20 and an inclination of 2 degrees from the plane of the ecliptic.[1] As of 2016, the asteroid's effective size, its composition and albedo, as well as its rotation period remain unknown.[1]
Based on an absolute magnitude of 16.5, the asteroid is calculated to measure between 1 and 3 kilometers in diameter, 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 body's reflectivity (albedo), the smaller its diameter, for a given absolute magnitude (brightness).[3]
The minor planet is named in honor of Hungarian amateur astronomer Ernő Berkó (b. 1955), who is interested in deep-sky objects and double stars. He is an independent discoverer of the supernova 1999by. The Washington Double Star Catalog contains more than 160 double stars discovered by him.[2]
