HIP 41378 is a star 347 light-years away with six planets. The star is an F6 type with an age of 4.28 billion years, a mass of 1.14 solar masses, a radius of 1.35 solar radii, and a temperature of 6200 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
HIP 41378 b, c, and d are Neptune-like planets, each with a radius and mass larger than Earth's. HIP 41378 b has a mass of 6.9 Earth masses, a radius of 2.64 Earth radii, and an orbital period of 15.6 days. HIP 41378 c has a mass of 5.97 Earth masses, a radius of 2.74 Earth radii, and an orbital period of 31.7 days. HIP 41378 d has a mass of 6.53 Earth masses, a radius of 3.65 Earth radii, and an orbital period of 278 days.
HIP 41378 e and f are Jupiter-like planets, both with a radius and mass larger than Earth's. HIP 41378 e has a mass of 7.62 Earth masses, a radius of 5.19 Earth radii, and an orbital period of 393 days. HIP 41378 f has a mass of 25 Earth masses, a radius of 9.47 Earth radii, and an orbital period of 542 days.
HIP 41378 g was discovered by radial velocity and has a minimum mass of 5.75 Earth masses and an orbital period of 63.2 days. Among the listed planets, HIP 41378 b has the shortest year at 15.6 days, HIP 41378 c has the second-shortest at 31.7 days, HIP 41378 e has the second-longest at 393 days, and HIP 41378 f has the longest at 542 days.
