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 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.{{cite journal |journal=Astronomy & Astrophysics |doi=10.1051/0004-6361:20077994 | volume=474 |issue=3|pages=1023–1029 |title=Survey of the stability region of hypothetical habitable Trojan planets |author1=R.
