764 Gedania (

rotation period of 24.98 hours. It was named after the Polish city of Gdańsk where the discoverer was an assistant at the observatory during the 1920s.[2]

Orbit and classification

Gedania is a non-

Heidelberg Observatory in November 1902, almost 11 years prior to its official discovery observation by Franz Kaiser.[1]

Naming

This

H 77). Asteroid 1419 Danzig was also named by its German name for the city of Gdańsk.[2]

Physical characteristics

In the

Small Solar System Objects Spectroscopic Survey (S3OS2).[5][11]

Rotation period

In February 2006, a rotational

U=2/2/2).[12][13][14]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

asteroid occultation of Gedania gave a best-fit ellipse dimension of (58.0 km × 58.0 km), with a poor quality rating of 1. These timed observations are taken when the asteroid passes in front of a distant star.[5]
