Witryna29 sty 2024 · A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers). On the scale of the universe, measuring distances in miles or kilometers doesn’t cut it. A light-year, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×10 km), or 5.88 trillion miles (5.88×10 mi). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the time-measurement word "year", the term light-year is sometimes misinterpreted as a unit of time.
WitrynaIn scientific usage, a light-year is a unit of length that is equal to the distance light travels in one year in the vacuum of space: about 5,878,000,000,000 miles.
