[10][11][15] Analysis of the two best-rated lightcurves gave a rotation period of 16.19 hours with a brightness amplitude of 0.58 and 0.44 magnitude, respectively (U = 3/3).
[7][8][9] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is an albedo of 0.2485 and a diameter of 56.22 kilometers based on an absolute magnitude of 8.38.
[4] This minor planet was named after the Hanseatic League (German: Hansa; Hanse), a medieval confederation of merchant guilds and market towns in Northern Europe and the Baltic region.
On the height of its expansion during the 14th and 15th century, the league included cities that are now located in Germany, Poland, Sweden, Estonia, Latvia, the Netherlands and Russia.
The name was proposed by astronomer Heinrich Kreutz in 1906, who was an editor of the journal Astronomische Nachrichten based in the German city of Kiel, which was a member town of the Hanse League.
