The light-year is a unit of length used to express astronomical distances. It is about 9.5 trillion kilometres or 5.9 trillion miles. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days). Because it includes the word year, the term light-year is sometimes misinterpreted as a unit of time.
Calculations are approximately done. The distance travelled by light in a year is 9 trillion km( accuratelyâ¦.9.461e+12). The distance between earth and moon is appr. 380000 km. We simply say it is 1.2 light second away. Because it is the distance distance traveled in 1.2second. It is somewhat weird to say it in km.
