(219) Thusnelda is an asteroid of the main asteroid belt , which was discovered on September 30, 1880 by Johann Palisa at the Pola marine observatory .
The asteroid was named after Thusnelda , the wife of the Germanic warrior Arminius .
Thusnelda moves at a distance of 1.8269 ( perihelion ) to 2.8816 ( aphelion ) astronomical units in 3.6122 years around the sun . The orbit is inclined 10.8412 ° to the ecliptic , the orbit eccentricity is 0.224.
Thusnelda has a diameter of 41 kilometers. It has a relatively light surface with an albedo of 0.201. It rotates on its own axis in around 29 hours and 51 minutes. It thus has a relatively slow rotation of its own.
