HD 188015 b

Extrasolar planet in the constellation Vulpecula

HD 188015 b is an extrasolar planet announced by the California and Carnegie Planet Search team in 2005.^[1] Like majority of known planets, it was discovered using the radial velocity method.

The planet has a minimum mass of about 1.25 Jupiter masses. It orbits HD 188015 in a slightly eccentric orbit with a semi-major axis about 20% further than Earth's.

Stability analysis reveals that if Earth-sized planets existed at the Trojan points of HD 188015 b, their orbits would be stable for long periods of time.^[2]
