Answer:
2.56 parsec
Explanation:
Parallax angle is the angle subtended by Earth over a gap of 6 months in its orbital path around the Sun with respect to a star. It can be used to measure the distance to the star.
[tex]d (parsec)=\frac{1}{p (arcsecond)}[/tex]
Given: p = 0.39"
Substitute the value:
[tex]d =\frac{1}{0.39"}=2.56[/tex] parsec
