description HD 3167 b Overview
HD 3167 b is a transiting super-Earth orbiting the K-type star HD 3167. It completes an orbit in roughly 23 hours and has a radius about 1.6 times that of Earth, placing it among the short-period rocky or volatile-rich planets found by transit surveys. Its bright host star and repeated transits make it a useful target for measuring planetary composition and studying whether a close-in atmosphere can survive intense stellar irradiation.
help HD 3167 b FAQ
What type of planet is HD 3167 b?
HD 3167 b is a transiting super-Earth with a radius about 1.6 times Earth's. It orbits the K-type star HD 3167 and belongs to the short-period planet population found by transit surveys.
How long is a year on HD 3167 b?
It completes an orbit in roughly 23 hours, so its year lasts less than one Earth day. Its extremely close orbit exposes the planet to intense stellar heating.
Can astronomers study the atmosphere of HD 3167 b?
The host star is relatively bright, which makes the system useful for follow-up observations. Whether the planet retains a substantial atmosphere depends on atmospheric loss and composition, which require detailed measurements.
Does HD 3167 b transit its star?
Yes, the planet was identified because it passes in front of HD 3167 and causes a measurable dip in starlight. Transit data provide its radius, while other observations can help constrain its mass and density.
