11573 Helmholtz, provisional designation 1993 SK3, is a Zhongguo
Lutz Schmadel at the Karl Schwarzschild Observatory in Tautenburg, Germany. It is one of few asteroids located in the 2:1 resonance with Jupiter. The asteroid was named for German physicist Hermann von Helmholtz.[2]
Orbit and classification
Helmholtz is a non-
It orbits the Sun in the
Crimea–Nauchnij in December 1982. The body's observation arc begins at Palomar Observatory in January 1989.[2]
Physical characteristics
Diameter and albedo
Based on a generic magnitude-to-diameter conversion, Helmholtz measures 13 kilometer in diameter for an
albedo of 0.057, which is typical for carbonaceous asteroids. If the body was of stony rather than carbonaceous composition, its estimated diameter would be less than 7 kilometer.[5]
