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.
For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.For nearby stars, the parallax method gives the most accurate measure of distances.

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.
