The Milky Way, also called the Galaxy, is a cluster of disk-shaped stars, which includes the Sun and its Solar System.

For a terrestrial observer, the disk of the Galaxy appears as a weakly luminous band that can be seen at night spreading across the sky, especially on clear and moonless summer nights. Formerly this band was called the Milky Way (also Camino de Santiago), a name that currently refers to the entire galaxy.

The Milky Way extends through the constellations Perseus, Cassiopeia and Cepheus. In the region of the Northern Cross, which is part of the Swan, it is divided into two currents: the western current that shines when it crosses the Northern Cross, pales near Ofiuco, because of dust clouds, and appears again in Scorpio; and the eastern current, which is brighter when it passes through the south through the Shield and Sagittarius.

The brightest part of the Milky Way extends from the constellation of the Shield to Scorpio, through Sagittarius. The galactic center is in the direction of Sagittarius and is about 26,000 light years from the Sun.
