It's really not clear what you're trying to ask here, since as stated the question is nonsensical: "star light" doesn't measure anything. Assuming that what you were trying to find out is how starlight is measured... the most accurate way is with a photometer.

How far are star?

Every star is a different distance. The distances are SO GREAT that we don't even measure them in miles - we measure them in light years, the distance light travels in a period of 365 days (almost six trillion miles)!! It's CRAZY !! The nearest star that we know of other than the Sun is about 4 light-years away.


Why do scientist measure light years for stars?

Scientists measure light from star in light years because almost every other units would be so small compared to the distance involved between stars. in fact the nearest star (other then the sun) is 24689699219682.054 miles or 39734219301000 km.


If a star is 61 lightyears what does that mean?

A Light Year is a measure of distance. If a star is 61 light years away, then it would take light (or radio waves, which travel at the speed of light) 61 years to get there.


What do you use to measure the distance to far away stars?

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.


What magnitude of a star is how bright it would be at a distance of 32.6 light years from earth?

That is called the absolute magnitude. It is a measure of the star's real brightness. Apart from the distance (10 parsec), another (implicit) assumption is that there is nothing in between that reduces the star's light.


How do you find the speed a star using Doppler shift?

To find the speed of a star using Doppler shift, you can measure the change in the wavelength of light emitted by the star. If the light is redshifted, the star is moving away from us; if it is blueshifted, the star is moving towards us. By analyzing the amount of shift, you can determine the star's speed relative to the observer.


What is the unit of measurement of the distances of the stars from the earth?

Light Year is unit for all astronomic distances


Why is light year convenient to use as a unit for measuring star distances?

Because, if we continued to measure the distances between star in miles, the numbers would be huge. One light-year is approximately equal to 5,865,696,000,000 miles !


The Doppler Effect is a phenomenon that allows one to measure an object's?

The doppler effect is the change in frequency of a wave for an observer moving relative to the source of the wave. You can measure the location and velocity of a locomotive moving towards or away from your. You can measure a star's location and velocity vector regarding the shift and color emanating from the star light. This is calculated via doppler light equations.
