Moscow oblast (MO) - not the most common example of subject of the Russian Federation: while the other regions tend to have a pronounced regional center, which is often the same name of the territory, in the Moscow region such a center is the city of Moscow, which has the status of a separate Federation subject.
As a result the Moscow region has a rather unusual shape: in the center of this area is located in the space, is not included in its composition. Thus, formally we can say that Moscow is one of the subjects of the Federation, which the Moscow oblast has a common border.
In total the region has more than 70 cities, of which about 20 have a population exceeding 100 thousand people. However, even these cities it's hard to call large, especially in comparison with Moscow: the most numerous are the Khimki and Balashikha, the population of each of which exceeds 200 thousand people.
