What Is Parallax? - How Astronomers Measure Stellar …

WebIntroduction – Parallax is defined as ‘the observed displacement of an object caused by the change of the observer's point of view’ (Lucas, 2024). Parallax is a phenomenon that occurs throughout astronomy, seen through calculating the distance of distant galaxies and stars from Earth. These calculations can also be done with normal objects on Earth to measure … Webθ (theta) = length of opposite side of triangle (Baseline) length of adjacent side (Distance) For this to work θ must be in radians, and the two lengths in the same distance units for the equation to be used.
