566 Stereoskopia

Stereoskopia (minor planet designation: 566 Stereoskopia) is a large, outer main-belt asteroid orbiting the Sun.[1] It was discovered on 28 May 1905 from Heidelberg by German astronomer Paul Götz.[2] The discovery was made from photographic plates with the use of a stereo-comparator that had been provided by Carl Pulfrich, a German physicist at the Carl Zeiss Company.[3] The asteroid name is a reference to this device.[2]

This object is a member of the Cybele group located beyond the core of the main belt.[1] It is orbiting at a distance of 3.39 AU with a period of 6.23 yr and an eccentricity of 0.12. The orbital plane is inclined at an angle of 4.9° to the plane of the ecliptic.[1] Light curve analysis based on photometric data collected during 2008 provide a rotation period of 12.103±0.002 h for this asteroid.[4] It spans a girth of approximately 167 km[1] and is classified as a carbonaceous C-type asteroid.[5]
