The closest star is the Sun - about 8 light-minutes away. The closest star after that is at a distance of 4.3 light-years; the farthest observable galaxies (galaxies are made up of stars) are at a distance of over 40 billion light-years.

What else can I help you with?
What is distance to stars usually called?
light year the DISTANCE light travels in a year so 'light year' is not a measure of time.
What units are for distance between stars?
The correct unit to describe the distance between stars is the "light year", the distance a photon of light would travel (through a vacuum) in a year.
Are light-years stars?
No. A light-year is a measurement. A light year is a distance measurement based on how far light travels in a year.
You measure the distance between stars in light years a light year is the distance that light travels in one year true or false?
That is correct.That is correct.That is correct.That is correct.
Why is using a light year useful for measuring stars?
Because the distance between stars is so great.
When do you use the term light year?
When talking about the distances that separate stars and galaxies. A light years is the distance that light travels in one year.
What is used to measure distance between stars?
Light year or astronomical units
Explain what a light year is and why great distances between stars are given in light years and not miles?
A light-year is the distance light travels in a year. Distances between stars are given in light-years because it is easier to visualize "10 light-years" (the distance travelled by light in 10 years), than "9.5 x 1213 kilometers".
What is a light year and why do scientist use it?
A light year is a measure of how far light can travel in one year. It is a phenomenal distance, and is used to describe how far away stars are from us.
Which distance would a light -year be most appropriate for measuring?
A light-year is most appropriate for measuring astronomical distances between stars and galaxies due to its vast scale. It represents the distance that light travels in one year, which is about 5.88 trillion miles.
Units used to measure the distance to stars in terms of whether their starlight takes minutes or years to reach earth?
The distance to stars is typically measured in light-years, which is the distance light travels in one year. Light-years are used because the distances to stars are vast and measuring in kilometers or miles would be impractical. For closer stars, distances can sometimes be measured in parsecs, which is another unit of distance based on trigonometric parallax.
Why do stars take so long to change?
The stars are light years away which is the distance light travels in a year. A light year is about 3x108km. The farther something is from you the slower they seem to travel so the stars don't look like the are moving. In reality, they are moving very fast.
