The answer is closer.
Parallax is used to determine how far a star is from earth by measuring its parallactic angle. If star a has a larger parallactic angle than star b, star a is closer than star b.
<h3>What is parallax?</h3>
When there is a difference in the direction of a celestial object as seen by an observer from two points which are widely separated, then this distance is termed as parallax.
This parallax measurement is used to find the distance of the body from Earth which is called Geocentric parallax and from the Sun which is called Heliocentric Parallax.
