Light years are used to measure the great distances of space. One light year is about 5.86 trillion miles. This is the distance light travels in one year's time.
You can use astronomical units or light years.
There are so many zeros in the value of light years when talking about a few light minutes. 1 light minute is 0.000001901 light years People do not like to talk about very small numbers and few know by heart that 1 year = 525948.766 minutes or that 1 year = 8765.81277 hours
Light years
Light years is a measurement of length (not time!), and was taken to use for the purpose of illustrating the wast distances in the galaxy and the universe. One light year is the distance in which light will travel during one year at the speed of Light ~3*10^8 m/s.
Light years is a measure for distance, the distance light travels in one year. For the light to travel 587 light years, it takes 587 years.
We use light years to tell us how fast light travels.
69 light years
Use this conversion: light-years x 9,460,730,472,580,800 = metres
Light years are used to measure distance from Earth to distant stars and planets.
Well, it is far easier to visualize "the distance light travels in 10 years" (i.e., 10 light years), than "9.5 x 1016 meters".
Ypu have to use scientific notation to the 10th power
No - a light year is a unit of distance - not time so you can't convert.
Light-years
Light years
We use light years for the sake of easy readability. In the universe, most of the distances are in trillions of miles or so. You cant go writing that an object is 1400000000000000... miles from earth! To make it clear and concise, light year is the unit we use.
one way is how far light travles in a year , (light years)
