1849 Kresak, provisional designation 1942 AB, is a carbonaceous asteroid from the outer region of the asteroid belt, about 26 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory in the middle of World War II on 14 January 1942.[5]
The asteroid orbits the Sun at a distance of 3.0–3.1 AU once every 5 years and 4 months (1,948 days). Its nearly circular orbit is inclined by 11 degrees to the ecliptic. It has a relatively long rotation period of 19 hours[4] and an assumed geometric albedo of 0.06 for a C-type asteroid.[3]
It was named in honor of Slovak astronomer Ľubor Kresák (1927–1994) from the Slovak Academy of Sciences in Bratislava and president of IAU's Commission 20 in the 1970s. He is well known for his theoretical work on meteors and the question of their relationship with comets and minor planets, as well as for the rediscovery of the short-period comet 41P/Tuttle–Giacobini–Kresák at the Skalnaté Pleso Observatory in 1951.[2]
