165 Loreley is a largemain-beltasteroid that was discovered byC. H. F. Peters on August 9, 1876, inClinton, New York and named after theLorelei, a figure inGerman folklore. It is orbiting theSun at a distance of3.125 AU and a loweccentricity of 0.08. Theorbital plane is inclined at an angle of 11.2° to theplane of the ecliptic.[2]
In the late 1990s, a network of astronomers worldwide gatheredlight curve data that was ultimately used to derive the spin states and shape models of 10 new asteroids, including (165) Loreley. The light curve of this asteroid varies by no more than 0.2 inmagnitude, while the derived shape model shows multiple flat spots on the surface.[4][6] The asteroid has an oblate shape with a size ratio of 1.26 ± 0.08 between the major and minor axes, as determined from theW. M. Keck Observatory.[7]
Between 2003 and 2021, 165 Loreley has been observed tooccult thirteen stars.
