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.
Satellites are used to measure the movement of plate by radiation.

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!
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.
It's pretty easy. They move west at approximately 15 degrees per hour. Outside of that (which is a result of Earth's rotation, not an actual movement of the stars), most stars don't move appreciably over a human lifetime.

They measure them in light-years.
The apparent movement of a star used to measure its distance from Earth is called parallax. Astronomers observe how a star's position changes relative to more distant stars as Earth orbits the Sun, allowing them to calculate the star's distance based on the angle of this shift.
