Web28 de mar. de 2024 · 1 ly or light year is the distance light travels in a year. It may sound as if it is a measure of time but it is actually a measure of distance. 1 light year is equal to 5,878,630,000,000 miles. It is much easier to think and calculate using light years when dealing with the enormous distances associated with the universe. WebCosmic Distances. In astronomy, distances are measured in units of light years, where one light year is the distance that light travels in a year—10 trillion kilometers. For historical reasons having to do with measuring distances to nearby stars, professional astronomers use the unit of parsecs, with one parsec being equal to 3.26 light years. chithirai natchathiram rasi
