1841 Masaryk, provisional designation 1971 UO1, is a carbonaceous asteroid from the outer region of the asteroid belt, about 46 kilometers in diameter. It was discovered on 26 October 1971 by Czech astronomer Luboš Kohoutek at Bergedorf Observatory in Hamburg, Germany.[8]
The asteroid orbits the Sun at a distance of 3.1–3.8 AU once every 6 years and 4 months (2,314 days). Its orbit is nearly coplanar with the ecliptic and only slighly eccentric (<0.1). It has a rotation period of 7.53 hours.[7] The geometric albedo of the C-type asteroid is in the range of 0.036 to 0.057.[3][4][5][6]
It was named in honor of the first president of the independent Czechoslovak Republic, Tomáš Garrigue Masaryk (1850–1937), statesman, philosopher and known for his humanistic ideas.[2]
