Question

what is known as parallax angle

Answer 1

Answer:

The parallax angle is the angle between the Earth at one time of year, and the Earth six months later, as measured from a nearby star. Astronomers use this angle to find the distance from the Earth to that star. ... Because of this, nearby stars will seem to move relative to distant, "background" stars.
