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.
light years are used as a type of measurement to calculate the distance between planets, astronomical units are used to measure how far away a planet is from earth.
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.

You don't really. You can just as well use the SI unit of length - the meter - and express the numbers in scientific notation. But most people prefer the smaller numbers that appear when using light-years or parsecs.
To measure the distance of stars you have to measure by light years.
Light years are used to measure distance from Earth to distant stars and planets.
you use light years, and other units
one way is how far light travles in a year , (light years)
Light years are a unit of distance used to measure vast distances in space. To measure light years, scientists use tools like telescopes and spectrographs to observe the light emitted by stars and galaxies. By analyzing the light's properties, such as its brightness and spectrum, scientists can calculate the distance to these celestial objects in terms of light years.
Light years, parsecs, and kiloparsecs. Light years and parsecs are used to measure distances between neighbouring star system's, kiloparsecs are used to measure distances within a galaxy.
No, 'years' is a measure of time and 'light years' is a measure of distance.
They don't. Light years are a distance measurement, not a time measurement.
