An instrument used to measure stars is called a spectrometer. It analyzes the light emitted or absorbed by stars, allowing astronomers to determine their composition, temperature, distance, and velocity. Another important tool is the telescope, which magnifies distant celestial objects, enabling precise observations and measurements of stars’ positions and brightness. Together, these instruments enhance our understanding of the universe.

Edwin Hubble used Cepheid variable stars to measure the distances to galaxies. These stars have a relationship between their luminosity and pulsation period, allowing astronomers to calculate their distance based on their observed brightness.
. . they are a convenient unit. Another convenient unit is the parsec.
Parallax is the apparent change in position of an object when you look at it from different angles. Astronomers often us parallax to measure distances to nearby stars. This method can be used to determine stars' distances up to 400 light-years from Earth.
The instrument commonly used to measure the gases in stars is called a spectrometer. This device analyzes the light emitted or absorbed by a star, breaking it down into its constituent wavelengths. By examining the resulting spectrum, astronomers can identify the chemical elements present and their abundance, as well as gauge the star's temperature, density, and motion.

A barometer.
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.
Yes.
It is not known what exact tools Tycho Brahe used to measure the planets and stars movements. He may have made special calculations by using some type of compass.
