The most distant stars we can currently measure stellar parallax for are approximately

Question

Quizplus · Accepted Answer

Stellar parallax is used to measure the distance to nearby stars by observing the apparent shift in position of the star over a six-month period as Earth orbits the Sun. The accuracy of this method decreases as the distance to the star increases, as the apparent shift becomes smaller and harder to measure. Currently, we can measure stellar parallax for stars up to about 1,000 parsecs away, so choice (A) is the best answer.
