We measure the movement of stars to study their motion within galaxies, determine their distances from Earth, and investigate their spectral shifts to learn about their composition and temperature. Studying the movement of stars also helps scientists understand the dynamics of galaxies and the evolution of the universe.
Satellites are used to measure the movement of plate by radiation.

to gaze up at stars and record movement.
One method to measure the distance to nearby stars directly is through stellar parallax. This involves observing a star from two different points in Earth's orbit around the Sun, and measuring the apparent shift in the star's position. The amount of shift allows astronomers to calculate the star's distance based on the geometry of the Earth-Sun-star triangle.

To measure the distance of stars you have to measure by light years.
All stars can be used to tell which direction you are travelling in as the movement of the earth is in a consistant direction, allowing you to compare your movement with the direction that the stars are travelling in.
Because they cannot visit stars and measure their sizes with a tape measure!
Satellites are used to measure the movement of plate by radiation.
While stars appear fixed from our perspective on Earth, they do have their own movement. The movement of stars across the night sky is due to the Earth's rotation. However, predicting the movement of stars in the long term would require complex calculations and consideration of factors such as their distance and speed.
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.
As far as I know, there is no measure of movement of air, but if you really are persistent, you can use balloons.
