Life Applications on Astronomy

Life Applications on Astronomy

Astronomy – measurement of the positions and movements 
The biggest impact that trigonometry has had in Astronomy is in the finding of distances to nearby stars through the method of parallax.

Parallax

  • When an object is viewed from two different positions it appears to move in relation to its background. This apparent movement is termed parallax. 
  • In astronomy, parallax refers to the difference in direction of a celestial object when viewed by an observer from two widely separated points.
                                                                             

Trigonometric Parallax

Parallax can be used directly to determine the distance of nearby stars.
