What is the relationship between stellar parallax (p)measured in seconds of arc and distance (d)measured in parsecs?
A) d = 1/p²
B) d = 1/p
C) d = p
D) d = p²

Question

Quizplus · Accepted Answer

The relationship between stellar parallax and distance is given as:

p (in seconds of arc) = 1/d (in parsecs)

Rearranging this equation, we get:

d = 1/p (in parsecs)

Therefore, the best choice is B.
