You are measuring the distance between our Solar System and the nearest star- which unit of measurement should you use?

When measuring the distance between our Solar System and the nearest star, the most appropriate unit of measurement is the light-year. A light-year is the distance that light travels in one year and is equivalent to approximately 9.46 trillion kilometers (about 5.88 trillion miles).

Given that the nearest star, Proxima Centauri, is about 4.24 light-years away from us, using light-years allows for a more manageable and comprehensible understanding of such vast distances compared to using kilometers or miles.

Other units like parsecs, which are often used in astronomy (1 parsec equals approximately 3.26 light-years), can also be used, but the light-year is the most common and straightforward for this context.
