Calculation

Lightyears

A light-year is a unit of astronomical distance, and it represents the distance that light travels in one year through the vacuum of space. Light travels at a speed of approximately 186,282 miles per second (299,792 kilometers per second) in a vacuum. The light-year is commonly used in astronomy to measure distances on a cosmic scale because of the vast distances involved in space. For example, the distance to nearby stars, galaxies, and other celestial objects is often expressed in terms of light-years due to the impracticality of using more familiar units like kilometers or miles for such immense distances.

Parsecs

A parsec (symbol: pc) is a unit of astronomical distance commonly used in astronomy to measure large distances between celestial objects. The term parsec is a combination of parallax and arcsecond, and its definition is based on the observed shift in position (parallax) of a star as seen from Earth over the course of a year. Parsecs are often used to express distances to nearby stars, galaxies, and other astronomical objects. In this context, they provide a convenient way to describe vast cosmic distances without dealing with extremely large numbers of light-years.
