HD 188015 b is an extrasolar planet announced by the California and Carnegie Planet Search team in 2005. Like majority of known planets, it was discovered using the radial velocity method.

The planet has a minimum mass about quarter greater than Jupiter. It orbits the star in a slightly eccentric orbit in a mean distance 20% further than Earth orbits the Sun.

Stability analysis reveals that the orbits of Earth-sized planets in the Trojan points of HD 188015 b would be stable for long periods of time.^[1]
