What is the estimated average planet population per star in the Milky Way galaxy according to accumulating evidence?
Answer
At least one planet per star.
The extensive cataloging of exoplanets over recent decades has led to the accumulation of strong evidence suggesting that planets are not rare occurrences but are extremely common throughout the galaxy. This body of evidence leads astronomers to estimate that, on average, there is at least one planet associated with every single star in the Milky Way. This high prevalence explains why thousands of exoplanets have been confirmed and indicates that our Solar System is likely representative of a common galactic outcome rather than a singularity.
