WISPIT 1 b
WISPIT 1 b is a cold gas giant orbiting the K4 V star WISPIT 1 in the constellation Puppis. It lies about 750 light-years from Earth and was discovered in 2025 using the imaging method.
Is WISPIT 1 b in the Habitable Zone?
The position of WISPIT 1 b relative to the habitable zone of WISPIT 1 cannot be precisely determined from the available orbital data.
Orbit and Year Length
WISPIT 1 b orbits at an average distance of 338.000 AU.
How Was WISPIT 1 b Discovered?
WISPIT 1 b was discovered in 2025 using the imaging method, with observations from Paranal Observatory.
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 WISPIT 1 b?
WISPIT 1 b is 750.2 light-years (230.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1276. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 13,203,520 years to make the journey.
The Host Star: WISPIT 1
WISPIT 1 b is a circumbinary planet — it orbits around two stars at once, like Tatooine in Star Wars.
