description HD 108874 b Overview
HD 108874 b is a gas-giant exoplanet orbiting the G-type star HD 108874. It was discovered through the radial-velocity method and has an orbital period of about 394 days, placing it near the distance from its star associated with the outer part of the habitable-zone region in some system models. The system also contains a second known planet farther out. The object is studied as a long-period giant around a star broadly comparable to the Sun.
help HD 108874 b FAQ
What is HD 108874 b?
HD 108874 b is a gas-giant exoplanet orbiting the G-type star HD 108874. It follows an orbit that takes about 394 days.
Why is HD 108874 b interesting for habitable-zone studies?
Its orbital period places it near the region associated with the outer part of the habitable zone in some models. That describes the planet's orbital location, not evidence that the gas giant can support life.
How was HD 108874 b discovered?
HD 108874 b was discovered with the radial-velocity method. Astronomers inferred its presence from the periodic motion of HD 108874.
Is HD 108874 b an Earth-like planet?
No. HD 108874 b is described as a gas giant, so it is not a rocky Earth analogue. Its position near a modeled habitable-zone region does not change its basic planet type.
