They use trigonometry to measure the parallax error in the nearby star's position based on a large triangle, the base of which is formed by two times the distance of the Earth to the Sun. Simply stated, they plot the star's position on one day, and again six months later, when the Earth is 186,000 miles away from its original position. They use the far distant stars as a calibration standard, and use the Pythagorean theorem to figure out the rest.
Location of a point on the surface of the earth.
this is called the absolute location
The exact position of a place derived from mathematical coordinates on the Earth's grid is the absolute location. The absolute location would be the latitude and longitude of a location.

The characteristic of a wave that describes the greatest distance it travels, or vibrates from a resting position is called the amplitude, which is the technical name. A more common name would be loudness.
Displacement is a vector quanity that measures the difference between final position and initial position. Distance is a scalar quanity the measures the total length traveled. For example, imagine you begin stationary at any location and walk along the outline of a 100ft circumference circle, returning you to your starting location. Your distance traveled will be 100 feet, your displacement will be 0 due to your initial position and final position being identical.
When measured, this distance (from normal to peak) is considered to be 1/2 of the amplitude. Amplitude is defined as the peak-to-peak distance.
The distance between the final position and the starting position is the
The location of an object is its position.
If an object is in motion than its position is changing.
A location is the position which is usually measure in terms of a fixed point of reference, which is called the origin. In n-dimensional space the location may be defined in terms of distances from origin along orthogonal axes (n axes), or in terms of distance and direction (one measure of distance and n-1 angles). Location on the surface of a sphere, for example the earth, can be defined by only two angles (the latitude and longitude) and no distance because the distance is implied (radius of the earth).
They are related because the position of a place or object is the location of that place or object.
