328 Gudrun is a largemain-beltasteroid. It was discovered by German astronomerMax Wolf on March 18, 1892, inHeidelberg. This minor planet is orbiting theSun at a distance of3.11 AU with aperiod of 5.486 yr and anorbital eccentricity of 0.106. Theorbital plane is inclined at an angle of 16.1° to theplane of the ecliptic.[2]
Analysis of thelight curve generated fromphotometric data collected in March 2012 provide arotation period estimate of10.992±0.002 h with a brightness variation of0.32±0.02 inB magnitude.[5] A study in 2022 found a classification of Cgh for 328 Gudrun, suggesting this is a dark, carbonaceous asteroid.[4]
