description HD 28185 b Overview
HD 28185 b is a giant exoplanet orbiting the Sun-like star HD 28185 in the constellation Eridanus. Its orbit takes about 383 days, giving it a period close to Earth's year, and its orbital distance places it within estimates of the star's habitable zone. The planet itself is not considered Earth-like because it is a gas giant, but its orbit makes the system relevant to studies of planetary formation and habitability.
help HD 28185 b FAQ
What is HD 28185 b?
HD 28185 b is a giant exoplanet orbiting the Sun-like star HD 28185 in the constellation Eridanus. Its orbit takes about 383 days.
Why is HD 28185 b often mentioned in discussions of habitable zones?
Its orbital distance falls within estimates of the habitable zone around HD 28185, and its period is close to Earth's year. That does not make the planet itself habitable because it is a giant planet rather than a known Earth-like world.
Is HD 28185 b similar to Earth because its year is about 383 days?
No. A roughly year-long orbit only compares the timing of its revolution with Earth's 365-day year. HD 28185 b is classified as a giant planet, so the comparison does not establish a rocky surface or Earth-like climate.
Which star does HD 28185 b orbit?
It orbits HD 28185, a Sun-like star in Eridanus. The planet's roughly 383-day orbit is one of the features that made the system notable.
