From what I remember in two geology classes, scientists measure the distance between a star and Earth by comparing "red shift," a shifting of certain bands of light toward the "red" end of the spectrum. The further the shifting, the greater the distance.
That is one of the things scientists use to help them measure a stars distance but it isn't just based on the color.
scientists use light-years to measure long distances in space. a light year, (abrviated ly) is the distance light can travel.
No, they are much too far away, and you would have a number too large to be usable.
Answer #1:no=================Answer #2:Yes.Another answer: The primary use of triangulation may not be to measure the distance of stars, but the method which is used to measure the distance of close stars is primarily triangulation.
To measure the distance of stars you have to measure by light years.
light years
The appliance of science
Distance.
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.
Kelvin (K)
You can measure it by using absolute magnitude.
With a long measuring tape.
