Quizplus · Accepted Answer

The astrometric technique involves measuring the small changes in a star's position due to the gravitational pull of an orbiting planet. This method works best for massive planets (Jupiter-like) around nearby stars because their gravitational influence on the star is stronger and easier to detect. Large planets (those with a large radius but low mass) do not necessarily have a strong enough gravitational pull to produce a measurable effect on the star's position. Also, detecting planets around distant stars is more challenging because their positions are harder to measure accurately.
