Answer:

2.56 parsec

Step-by-step 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.


d (parsec)=(1)/(p (arcsecond))

Given: p = 0.39"

Substitute the value:


d =(1)/(0.39 parsec
