Distance measurement in Astronomy
... You can find the distances of stars that are ‘relatively close’ to the Earth using parallax. A very simple example of parallax is to hold one forefinger upright about 30 cm in front of your nose and close your right eye. Using just your left eye line up your forefinger with an object on the other si ...
