Perhaps you mean the satellite Hipparcos. It measured the position of over 100,000 stars with high precision. It also measured the position of 2.5 million stars, with lower precision.

light years
The stars make excellent navigation aids, if you have the proper instruments to measure their locations.
light years
Light years or parsecs

To measure the distance of stars you have to measure by light years.
We use, in many remarkable ways, the [Spectrophic] Light obtained by telescopes.
Because they cannot visit stars and measure their sizes with a tape measure!
We have no idea how many stars there are. At a rough guess, scientists estimate that there may be 2 trillion stars in the Milky Way galaxy, and that there may be a trillion other galaxies. There is no way to measure it in any meaningful way.
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.
Magnitude.
light years
They measure them in light-years.
Hipparchus' discoveries in astronomy were important because he developed the first systematic model of the motion of the Sun and Moon, and compiled one of the earliest known star catalogs with over 850 stars. His work laid the foundation for future astronomers and greatly contributed to the understanding of celestial movements.
You can measure it by using absolute magnitude.
The sun, the stars.
