Шаблон:About Шаблон:Infobox planet

Garumna (minor planet designation: 180 Garumna) is a main belt asteroid that was discovered by the French astronomer Henri Joseph Perrotin on January 29, 1878.[1] Its name comes from the ancient Latin name for the Garonne River in France. In the Tholen classification system, it is categorized as a stony S-type asteroid, while the Bus asteroid taxonomy system lists it with the Sr sub-type.[2]

The rotation period of this asteroid is very nearly equal to that of the rotation of the Earth. This means that only a small portion of the light curve can be observed from any one location, requiring measurements from multiple sites in order to build a complete curve. In 2012, this mission was accomplished, giving a period of 23.866 ± 0.001 hours with a brightness variation of 0.42 ± 0.02 in magnitude. Allowing for a margin of error and changes in phase angle, this finding agrees with previous measurements made in 2008 and 2011.[3]
