How Far Is A Light Year

Light travels at a speed of 186 000 miles.
How far is a light year. A light second is the distance light travels in one second or 7 5 times the distance around earth s equator. A light year is a standard of measurement used by astronomers to describe huge distances in the universe. The nearest star is 4 22 light years away. The light year is a measure of distance not time.
A light year is the distance light travels in one earth year. That is a 6 with 12 zeros behind it. A light year is the distance traveled by a light in a vacuum within a julian year 365 25 days a light year can also be described as an astronomical unit of measuring astronomical distances in space. The center of the milky way is about 26 000.
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. Light travels a whopping 9 460 528 000 000 km in a year equivalent to 5 878 499 562 555 miles. The light year is a unit of length used to express astronomical distances and measures about 9 46 trillion kilometres 9 46 x 10 12 km or 5 88 trillion miles 5 88 x 10 12 mi. So how far does light go in a year.
Looking back in time. Because it includes the word year the term light year may be. Those are really large numbers. One light year is about 6 trillion miles 9 trillion km.
A light year is the distance light travels in one year. When we use powerful telescopes to look at distant objects in space we are actually looking back in time. How far is 40 light years. How far is that.
How can this be. It is the total distance that a beam of light moving in a straight line travels in one year.
