1855 Korolev, provisional designation 1969 TU1, is a stony asteroid from the inner regions of the asteroid belt, about 7 kilometers in diameter. It was discovered by Russian female astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on 8 October 1969.[7]
The asteroid orbits the Sun at a distance of 2.1–2.4 AU once every 3.37 years (1,230 days). Its low-eccentric orbit is inclined by 3.1 degrees to the plane of the ecliptic.[1] It has a rotation period of 4.66 hours.[5] Preliminary analysis of WISE/NEOWISE missions found a geometric albedo for the S-type asteroid of 0.319±0.032, while the Light Curve Database project assumes a lower figure of 0.24.[3][4]
It was named in honor of Sergei Korolev (1907–1966), an outstanding designer, integrator, organizer and strategic planner. He was the lead Soviet rocket engineer and spacecraft designer in the Space Race between the United States and the Soviet Union during the 1950s and 1960s until his early death. The lunar and Martian craters Korolev are also named in his honour.[2]
