HIP 39330 b
HIP 39330 b is a cold gas giant orbiting the G5 V star HIP 39330 in the constellation Puppis. It lies about 119 light-years from Earth and was discovered in 2026 using the radial velocity method.
Is HIP 39330 b in the Habitable Zone?
The position of HIP 39330 b relative to the habitable zone of HIP 39330 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on HIP 39330 b — one full orbit around HIP 39330 — lasts 4,650.0 Earth days, longer than Jupiter's 12-year orbit. It orbits at an average distance of 5.050 AU. Its orbit is mildly elliptical (eccentricity 0.08).
How Was HIP 39330 b Discovered?
HIP 39330 b was discovered in 2026 using the radial velocity method, with observations from Multiple Facilities.
The radial velocity method measures the subtle wobble of a star caused by the gravitational pull of an orbiting planet, visible as periodic shifts in the star's light spectrum. The size of the wobble reveals the planet's minimum mass.
How Far Away Is HIP 39330 b?
HIP 39330 b is 118.7 light-years (36.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1908. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 2,089,120 years to make the journey.
