1856 Růžena, provisional designation 1969 TW1, is a stony asteroid from the inner regions of the asteroid belt. It was discovered on 8 October 1969, by Russian female astronomer Lyudmila Chernykh at Crimean Astrophysical Observatory in Nauchnyj.[3]
The asteroid orbits the Sun at a distance of 2.1–2.4 AU once every 3.35 years (1,222 days). Its orbit has an eccentricity of 0.08 and an inclination of 4.7 degrees. Little is known about the size, rotation and albedo of the S-type asteroid.[1]
It was named in honor of Růžena Petrovicova, observer of comets and minor planets and staff member of the Kleť Observatory, located in what is now the Czech Republic.[2]
