What is the parallax formula for astronomy? What is the unit of measurement for the formula?
Parallax is the apparent angular displacement of a space body due to displacement of the position of the observer. As of now, the unit for this angular measure could be
The unit for parallax depends on the precision of the device used for the measurement. The smallness varies. Currently, the accuracy level is up to 0.001 sec =
Parallax is used to approximate distances of space bodies.
