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.

How to measure light years and what tools are used for this purpose?

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.
