Star City lies 40 km northeast of Moscow. The central circle of Star City is home to the Yuri Gagarin Cosmonaut Training Centre, which was founded in 1960. All generations of cosmonauts that have gone into space, from Yuri Gagarin and Valentina Tereshkova onwards, trained in the centre.

Alongside the central circle, equipped with research laboratories, training facilities, institutes and administration buildings, the second circle is home to the residential infrastructure, which allows the population of the city to lead a full modern life.
