STELLAR PARALLAX Meaning and
Definition
-
Stellar parallax refers to the apparent shift or change in the position of a star when observed from different locations in space. It is a fundamental concept in astronomy used to determine the distance of stars from Earth, as well as mapping the structure of the universe.
The phenomenon of stellar parallax occurs due to the Earth's orbit around the Sun. As the Earth moves from one side of its orbit to the other over the course of six months, stars appear to shift minutely against the background of more distant stars. This displacement is known as stellar parallax and is measured by comparing the positions of a star in the sky when observed six months apart.
The concept of stellar parallax is based on trigonometry. By measuring the angular shift of a star, astronomers can calculate its distance using the principles of triangulation. The smaller the parallax angle, the greater the distance of the star from Earth. This understanding allows astronomers to create a relative scale of distances in our galaxy, the Milky Way, and beyond.
Stellar parallax serves as a crucial technique for determining the distance of nearby stars, allowing for the calculation of their intrinsic properties such as luminosity and size. It provides a foundation for understanding the broader universe and the vast distances between celestial objects. Moreover, advancements in technology have further improved the accuracy of measuring stellar parallax, leading to more precise distance determinations and a deeper understanding of the cosmos.

Etymology of STELLAR PARALLAX
The word "stellar" originates from the Latin word "stella", meaning "star". The term "parallax" is derived from the Greek word "parallaxis", which refers to the change in apparent position of an object when viewed from different perspectives. Therefore, the term "stellar parallax" combines these two words to describe the phenomenon of the apparent shift in the position of stars when viewed from different locations on Earth.
