Abstract
The Sun is the star closest to us and the only star where details can be directly observed. By comparison of the parameters describing the Sun with other stars, we understand the physics of stars in more detail and by comparing e.g. our present Sun with stars that are younger or older than the Sun, we can learn about the evolution of the Sun, its formation, and its ultimate fate.
