Question

If given 17.0, 1.4, 5.0 in parsecs (distance from earth) how do you find the parallax angle in arcseconds?

Answer 1

. 1\17s, 1\ 1.4.1/5s, respectively.

, Here, the circular arc-spacing, between two locations for observation, remains the same. The center moves away from the observer(s).

(Distance in parsec) X (Angle in sec) = 1.

So, the parallax angles will be the reciprocals of the distances,
