context_page_description: 1419 Danzig is a highly elongated Flora asteroid from the inner regions of the asteroid belt. It was discovered on 5 September 1929, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany. The stony S-type asteroid has a rotation period of 8.1 hours and measures approximately 14 kilometers in diameter. It was named for the city of Gdańsk.
context_section_description: In November 1988, Polish astronomer Wiesław Wiśniewski obtained a rotational lightcurve of Danzig from photometric observations. It gave a well-defined rotation period of 8.0±0.1 hours with a brightness variation of 0.92 magnitude (U=3). In October 2002, another lightcurve obtained by Italian and French amateur astronomers Silvano Casulli and Laurent Bernasconi gave a concurring period of 8.1202±0.0001 hours and an amplitude of 0.81 magnitude (U=3). While Danzig has an average rotation period, it has a high brightness variation, which indicates that the body has a non-spheroidal shape. In 2011, a modeled lightcurve using data from the Uppsala Asteroid Photometric Catalogue (UAPC) and other sources gave a period 8.11957±0.00005 hours, as well as a spin axis of (22.0°, 76.0°) in ecliptic coordinates (λ, β) (U=n.a.).
