The Milky Way’s 100 Billion Planets

This artist’s illustration gives an impression of how common planets are around the stars in the Milky Way.

A six-year search that surveyed millions of stars using the microlensing technique concluded that planets around stars are the rule rather than the exception. The average number of planets per star is greater than one. This means that there is likely to be a minimum of 1,500 planets within just 50 light-years of Earth.
