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.
Whirlpool galaxy (M51): 37,000,000 miles. Sombrero galaxy (M104): 65,000,000 miles. Astronomers measure the distance to the Andromeda galaxy using light-years. One light-year equals about 6 trillion miles. This galaxy is over 2 million light-years from Earth.tars other than our sun are so far distant that astronomers refer to their distances not in terms of kilometers or miles â but in light-years. Light is the fastest-moving stuff in the universe. It travels at an incredible 300,000 kilometers (186,000 miles) per second. Thatâs very fast.
