191 Kolga
191 Kolga is a large, dark main-belt asteroid that was discovered by German-American astronomer C. H. F. Peters on September 30, 1878, in Clinton, New York. It is named after Kolga, the daughter of Ægir in Norse mythology.〔 In 2009, Photometric observations of this asteroid were made at the Palmer Divide Observatory in Colorado Springs, Colorado. The resulting light curve shows a synodic rotation period of 17.625 ± 0.004 hours with a brightness variation of 0.30 ± 0.03 in magnitude. Previous independent studies produced inconsistent results that differ from this finding.〔 ==References==
