43954 Chýnov, provisional designation 1997 CT5, is an asteroid from the inner regions of the asteroid belt, roughly 6 kilometers in diameter. It was discovered by the two Czech astronomers Miloš Tichý and Zdeněk Moravec at the Kleť Observatory in South Bohemia, on 7 February 1997.[2]
The asteroid orbits the Sun at a distance of 2.1–2.4 AU once every 3 years and 5 months (1,251 days). Its orbit shows a low eccentricity of 0.06 and is tilted by 7 degrees to the plane of the ecliptic.
Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty – a condition code of 0 – and an observation arc that spans over a period of two decades.[1] Based on its absolute magnitude of 14.3, its diameter could be anywhere between 4 and 8 kilometers, assuming an albedo in the range of 0.05 to 0.25.[3] Since inner-belt asteroids typically have a spectral type of a brighter rocky, rather than a darker carbonaceous body, its true diameter may be at the lower end of NASA's generic conversion table, as, for a given absolute magnitude, an object's diameter decreases, when its albedo increases.[3]
The minor planet is named after Chýnov, a south Bohemian village in the Czech Republic, well known for its limestone cave, Chýnovská jeskyně.[2]
