HIP 39017 b
HIP 39017 b is a exoplanet orbiting the A9/F0 star HIP 39017 in the constellation Monoceros. It lies about 216 light-years from Earth and was discovered in 2024 using the imaging method.
Is HIP 39017 b in the Habitable Zone?
The position of HIP 39017 b relative to the habitable zone of HIP 39017 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on HIP 39017 b — one full orbit around HIP 39017 — lasts 31,000.0 Earth days, longer than Jupiter's 12-year orbit. It orbits at an average distance of 22.100 AU. Its orbit is highly elliptical (eccentricity 0.55), swinging dramatically closer to and farther from its star.
How Was HIP 39017 b Discovered?
HIP 39017 b was discovered in 2024 using the imaging method, with observations from Multiple Observatories.
Direct imaging captures actual pictures of a planet by blocking out the overwhelming glare of its host star. It works best for young, hot, massive planets on wide orbits.
How Far Away Is HIP 39017 b?
HIP 39017 b is 216.3 light-years (66.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1810. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 3,806,880 years to make the journey.
