Of all the stars with metal abundances like the Sun surveyed so far by the radial velocity method, about how many have planets in orbit around them?

Question

Quizplus · Accepted Answer

Based on current research, the radial velocity method has found that approximately 10%-20% of stars with metal abundances similar to the Sun have planets in orbit around them. While this percentage may increase as technology improves and new detection methods are developed, the current estimate is still a relatively small fraction.
