No because the wavelength is determined by the star radiating the light.
But over large distances from far-off galaxies there is a slight shift in the wavelength called the red shift, and the distance can be measured by the amount of red shift.

Douglas Adams The Hitchhiker's Guide to the Galaxy
We can use any units of measure we like discuss astronomical distances; miles, kilometers, furlongs, stadia; the problem is that if we use the same distance units for space that we use to measure things on Earth, the numbers are enormous; almost incomprehensible, even to scientists.
So we use a really big unit of measure - the distance that light travels in a year - for our unit of measure. Then astronomical distances don't SEEM quite so large.

∙ 11y agoYes, light years measure the distance between stars, galaxies and other heavenly bodies and far away objects in the universe. Since the distance between these is too vast, light years are used to denote them. A light year is approximately 10 trillion kilometers. According to the International Astronomical Union (IAU) one light year is the distance that light travels in vacuum in one Julian year (365.25).
Wiki User
∙ 14y agoYes. Light years are used due to the vast distances between the stars. Another method used by scientist is a parsec which is equal to 3.26 light years.
Wiki User
∙ 13y agoYes, since the distances are so large. You wouldn't be able to easily compare distances or appreciate them if they were in miles or km.

Which distance would a light -year be most appropriate for measuring?
Any distance larger than an inconvenient number of billions of miles. The light-year itself is about 5,979 billion miles.
Units used to measure the distance to stars in terms of whether their starlight takes minutes or years to reach earth?
Tbhe unit is the "light year" = 5.8787 x 1012 miles
Does light year denote distance on earth?
No. A light year measures such large distances that it would be highly impractical to measure anything on Earth. The light year is used to measure distance in space beyond the solar system.
What unit have astronomers chosen to measure the distance to stars?
Light years and parsecs. A light year is approximately 9,470,000,000,000,000 meters (9.47x10^15) and a parsec is roughly 3.26 light years
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.
What is used to measure distance between stars?
Light year or astronomical units
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.
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.
Why is the light year used to measure the distance between the stars and us instead of kilometres?
it is so far that kilometers wont work
How is light years used in science measurement?
A light year is the distance light travels in a year. That is roughly 6,000,000,000,000 miles (six trillion miles). Thus such a unit is used only to measure the largest distances, those between stars and galaxies.
What do astronomers use to measure distance to stars?
If you refer to the units, both the light-year and the parsec are often used. A light-year is the distance light travels in a year; about 9.5 x 1012 kilometers (9.5 million million kilometers). A parsec is about 3.26 light-years.
What is a light-year and when is used most conveniently?
Its the distance light travels in a year, and its used to measure stellar distances.
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 was a light year made?
The light year is often used to measure distances to stars and other distances on a galactic scale, especially in nonspecialist and popular science publications.A light year is a unit of length, equal to just under 10 trillion km.As defined by the International Astronomical Union, a light year is the distance that light travels in a vacuum in one year.
What unit of measure is most often used to describe distances to other stars beyond the sun?
-- "Light Year" for the closer ones -- "Parsec" for the farther ones
Which distance would a light -year be most appropriate for measuring?
Any distance larger than an inconvenient number of billions of miles. The light-year itself is about 5,979 billion miles.
Unit used to measure the distance of stars?
Light years (the distance that light travels in one year) and parsecs, which is approximately equal to 3.26 light years. For very distant objects, the units of "mega-parsecs" (millions of parsecs) are sometimes used, sometimes abbreviated as "Mpc".
