HD 154088 and Its Planet
HD 154088 is a K1V star, a K-type main-sequence dwarf, located 59.6 light-years from Earth. It is older and somewhat less massive and smaller than the Sun: its age is 12.5 billion years, its mass is 0.92 solar masses, its radius is 0.95 solar radii, and its temperature is 5410 K. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
One planet orbits this star. HD 154088 b was discovered in 2021 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 6.6 Earth masses, larger than Earth's, and its orbital period is 18.6 days.
