Explain Parallax method to determine diameter of a star & the distance of planet
Answers
Parallax is a method based on measuring two angles and sides of a triangle formed by the star, earth on one side and the other side six month later. Astronomers find the distance of nearby stars in the space by using a parallax method. ... Its apparent displacement by comparing the distance of star respect to the earth.
Answer:
Parallax is the displacement or the change in the apparent position of the object when viewed from two different points of view.
The two points of view have their own line of sights and parallax is measured as half of the angle between the two lines of sights.
When you are traveling in a vehicle and you look around as you are moving, you will see that objects in the distances appear to move more slowly than the objects closer to you.
This is the effect of parallax. Nearby objects have a larger parallax than the distant objects, so the parallax can be used to determine distances.
