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!

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.
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.

They measure them in light-years.

As far as I know, there is no measure of movement of air, but if you really are persistent, you can use balloons.
