Histogram of metallicities of planet‐bearing stars (solid line), compared to the nearest field stars (dashed line). The majority of the planet‐bearing stars are metal‐rich relative to the Sun, which is itself metal‐rich relative to nearby field stars. The metallicities of the Sun, HD 52265, and BD −10°3166 are indicated from left to right by the tick marks at [Fe/H] = 0.00, 0.11, and 0.50, respectively.
