Polotsk

Polotsk (Polatsk, Belarusian: По́лацк, Russian: По́лоцк, Polish: Połock) is a historical city in Belarus, situated on the Dvina River. It is the center of the Polatsk Raion in Vitsebsk Voblast. Its population is more than 80,000 people. It is served by Polotsk Airport and during the Cold War was home to Borovitsy air base.

History

The Old East Slavic name, Polotesk, is derived from the Polota River, that flows into the Western Dvina nearby. The Vikings rendered that name as Palteskja.

Polotsk is one of the most ancient cities of the Eastern Slavs. The Primary Chronicle listed Polotsk in 862 (as Полотескъ, /poloteskŭ/), together with Murom and Beloozero. However, there is debate about this, as some historians believe Polotsk was not yet in existence in the 9th century, and this record was an invention of the compiler. However, an archaeological expedition from the Institute of History of the National Academy of Sciences of Belarus suggests that Polotsk did exist in the first half of the 9th century.

List of craters on Mars: O-Z

This is a list of craters on Mars. There are hundreds of thousands of impact crater on Mars, but only some of them have names. This list here contains only named Martian craters starting with the letter O – Z (see also lists for A – G and H – N).

Large Martian craters (greater than 60 km in diameter) are named after famous scientists and science fiction authors; smaller ones (less than 60 km in diameter) get their names from towns on Earth. Craters cannot be named for living people, and small crater names are not intended to be commemorative - that is, a small crater isn't actually named after a specific town on Earth, but rather its name comes at random from a pool of terrestrial place names, with some exceptions made for craters near landing sites. Latitude and longitude are given as planetographic coordinates with west longitude.
