Hello Aspirant,

Paralllax method is also known by the names of stellar parallax and parallax trignometric. Parallax is one of the most important distance measurement methods used by astronomers. It can only be used for nearby stars, but it is very accurate. The method works by measuring at the apparent movement of a nearby object against the background of a distant object.

For e.g. While exploring some rocky cliffs, you notice a lighthouse in the distance that you can't quite reach. It would be nice to know how far away that lighthouse is, but there is no way to make a direct measurement over the uneven terrain. Luckily you have your trusty compass and some knowledge about parallax and triangles.

I hope this information helps you.

Good Luck!!
