When we talk about the enormity of the cosmos, its easy to toss out big numbers but far more difficult to wrap our minds around just how large, how far, and how numerous celestial bodies really are. [3] The unit most commonly used in professional astronomy is the parsec (symbol: pc, about 3.26 light-years) which derives from astrometry; it is the distance at which one astronomical unit subtends an angle of one second of arc.[2]. Distances expressed in light-years include those between stars in the same general area, such as those belonging to the same spiral arm or globular cluster. To get a better sense, for instance, of the true distances to exoplanets planets around other stars we might start with the theater in which we find them, the Milky Way galaxy.
