Which of these is most likely to happen if parallax measurements of star distances are taken after a gap of six months? The results would be accurate the results would be inconsistent the results would not be valid the results would not be repeated

Option A, The results would be accurate

Explanation:

The distance between two stars is measured using the trigonometric parallax method in which the brightness of stars is used as a distance measurement parameter.

Parallax method is used when the stars are very near. The parallax will produce inconsistent result only when the stars are moving at a very rapid speed in diverse direction. Since this is not happening in this case, thus, accurate results will be obtained even after six month

Option A, is correct
