The international group of astronomers from the USA and Spain has explained origin of an astronomical object of Segue 1 which as it is considered, is the dwarfish spheroidal galaxy or a spherical congestion. According to researchers, it is more probable that Segue 1 represents the galaxy occupied by gravitation of the Milky Way. The Science Alert.Segue 1 edition — the dim satellite of our Galaxy reports about it, and its luminosity is no more than total luminosity of 300 Sun that it isn't enough for a typical spherical congestion. It consists of old stars with the low content of metal that indicates that the possible galaxy has arisen in the early Universe when the first or second generation of stars didn't become supernew yet, synthesizing and extending heavy elements. Researchers have calculated a trajectory of Segue 1 and have found out that an object rotates around the Milky Way with frequency of 600 million years. It is characteristic of the dwarfish galaxy. According to the most probable scenario of her emergence, about eight billion years ago Segue 1 has been taken by our Galaxy.
