Question

Quizplus · Accepted Answer

The astrometric technique, which measures the tiny movements of a star as it is affected by the gravitational pull of an orbiting planet, works best for massive planets around nearby stars. This is because more massive planets exert a stronger gravitational pull on their host stars, causing more noticeable movements that are easier to detect, especially when the star is closer to us.
