Light Year Definition The Milky Way Galaxy Amnh A light year is the distance light travels in one earth year, about 6 trillion miles. learn how we use light years to measure the distance of objects in space and how they relate to time and space. A light year, alternatively spelled light year (ly or lyr[3]), is a unit of length used to express astronomical distances and is equal to exactly 9 460 730 472 580.8 km, which is approximately 9.46 trillion kilometres or 5.88 trillion miles.
Light Year Definition The Milky Way Galaxy Amnh A light year is the distance light travels in a vacuum in one earth year. learn how to measure distances in light years, parsecs, and astronomical units, and see examples of objects in different units. Light year, in astronomy, the distance traveled by light moving in a vacuum in the course of one year, at its accepted velocity of 299,792,458 metres per second (186,282 miles per second). A light year is the distance light travels in a vacuum over the course of one year. multiply the speed of light by the number of seconds in a year, and you get the magic number: about 9.46 trillion kilometers, or roughly 5.88 trillion miles. A light year is the distance that light travels in one year, which is about 5.88 trillion miles. learn how astronomers use light years to measure and compare the vast distances in space, and what are some common misconceptions about this unit.
