A galaxy is a massive, bonded, gravitational system of stars (with all its manifestations, including neutron stars and black holes), interstellar gas and interstellar dust, and dark matter-an important but not very well-understood component. The word galaxy comes from the Greek galaxias (γαλαξίας), which means "like milk," which refers to the Milky Way (English: Milky Way). The galaxies range from dwarf galaxies with only ten million (107) stars to giant galaxies with a hundred trillion (1014) stars, all orbiting at the centers of their respective galaxy's masses. The Sun is one of the stars in the Milky Way; the solar system including the earth and all the objects orbiting the Sun.

Each galaxy has a diverse number of star systems and clusters of stars, as well as the type of interstellar clouds. Among these galaxies are scattered interstellar mediums of gas, dust, and cosmic rays. The supermassive black holes are at the center of most galaxies. It is estimated that supermassive black holes are the main cause of active galactic nuclei found in some galaxies. The Milky Way Galaxy is known to have at least one supermassive black hole.

Historically galaxies are grouped by their visible form or commonly called visual morphology. The common form is the elliptical galaxy, which has an ellipse-shaped light profile. Spiral galaxies are disk-shaped galaxies with galactic arms that are dilengkunng and contains dust. Galaxies with irregular or unusual shapes are called irregular galaxies and are usually caused by disturbances by the gravitational pull of neighboring galaxies. Such interactions between adjacent galaxies can lead to merging, which sometimes increases the amount of star formation to produce starburst galaxies.

There may be more than 170 billion (1.7 × 1011) galaxies in the observable universe. Most are 1000 to 100,000 parsec in diameter and are usually separated by a distance of several million parsecs (or megaparsecs). The intermediate space is filled by a thin gas with a mass density of less than one atom per cubic meter. Most galaxies are organized into a hierarchy of sets called groups and clusters, which in turn form a larger set of so-called giant clusters. In the largest scale these sets are generally arranged in layers and strands surrounded by a vast void.

Although not yet comprehensively understood, dark matter is likely to make up about 90% of the mass of most galaxies. Observational data suggest that supermassive black holes may be at the center of many (if not all) galaxies.
