HD 132406 b is a long-period, massive gas giant exoplanet orbiting the Sun-like star HD 132406. HD 132406 b has a minimum mass 5.61 times the mass of Jupiter. The orbital distance from the star is almost twice that of from Earth to the Sun. The orbital period is 2.7 years.
An astrometric measurement of the planet's inclination and true mass was published in 2022 as part of Gaia DR3, and this was updated in 2023.
