# How does distance affect stellar parallax?

Inversely proportional to the distance.

The relation is parallax angle varies as the reciprocal of the

distance.

Smaller the angle, longer is the distance.

directions in which the same star is observed from the same place

on the Earth in a time-gap of 1/2 year, the distance of the star is

If the star is the ( nearest to us ) Sun, the distance 1 AU=(2/alpha)

us, Proxima Centauri is at a distance of 4.246 light years = 63242 X

4.246 AU= 268526 AU, nearly. This parallax angle ( measured in a

time gap of 1/2 year) will be 2/268526 radian = 0.00000745

radian = 1.5'', nearly.

Because parallax is the apparent shift in a star's position caused by the Earth's motion around the Sun, and because the angle of this shift decreases with increasing distance to a star, the farther away a star is, the smaller its parallax angle, and vice versa.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
