What is the difference between triangulation and parallax

CompareWords Compare. What's the difference between parallax and triangulation? Parallax Definition: n. The apparent displacement, or difference of position, of an object, as seen from two different stations, or points of view. The apparent difference in position of a body as the sun, or a star as seen from some point on the earth's surface, and as seen from some other conventional point, as the earth's center or the sun.

So, let's start learning about measuring distance by triangulation and parallax methods in detail. Before going to learn about the parallax method, let's have a glance at the triangulation method with an example. The parallax method uses the triangle to describe the distance or length between Stars.

Let's discuss how it will be. The triangulation method refers to the process of finding the values of three elements required to form a triangle and is used to find the distance or location of an object in space. Along with astronomers, their triangulation method is also used by surveyors and architects. When the distance or location of your point is unknown, they use this triangulation method to find out that point of location by using the other two points.

The triangulation example helps to get a clear idea about measuring distance by triangulation. Let's find the distance of a ship from the shore using the triangulation method. Let us consider two linear points on the shore as a baseline AB. These are the angles from seashore to ship. By substituting all these values, we can find the direct distance from the ship to the seashore.

Using the principle of triangulation method, the distance measurement by parallax method will be done. Several astronomers benefited from the Parallax method. The Parallax metal refers to the apparent change in position of the object in space when viewed from two different points of position. That's the reason, the parallax method takes half of both angles at both points.

This forms a triangle and leads to the usage of the triangulation method. For instance, if we observe from a vehicle, the other closer objects move faster and the farther objects move slower. This difference happened because of observation. Hence, the parallax method is the best way to measure the distance between Stars. It was recommended by several astronomers.
