The Milky Way is a barred spiral galaxy 100,000–120,000 light-years in diameter containing 200–400 billion stars. The galaxy is estimated to contain at least as many planets, 10 billion of which could be located in the habitable zone of their parent star. The Milky Way is part of the Local Group of galaxies. The galaxy consists of a bar-shaped core region surrounded by a disk of gas, dust and stars forming four distinct arm structures spiraling outward in a logarithmic spiral shape, commonly referred to as the "spiral arms." The Milky Way is part of the "Local Group" galaxy cluster, with the Andromeda galaxy being the next closest spiral galaxy to our own.
