HIP 54597 and Its Planet

HIP 54597 is a K5 V star 130 light-years away. Its spectral type marks it as a main-sequence dwarf. The star is 6.9 billion years old, with a mass of 0.69 solar masses and a radius of 0.66 solar radii. Its temperature is 4800 K, and its reported mass, radius, and temperature are all smaller or cooler than the Sun's.

One planet orbits this host. HIP 54597 b was discovered in 2023 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet's mass is 763 Earth masses, roughly 2.4 times Jupiter's mass, and larger than Earth's. Its orbital period is 3270 days.
