WISE J033605.05-014350.4 b
WISE J033605.05-014350.4 b is a cold gas giant orbiting WISE J033605.05-014350.4 in the constellation Eridanus. It was discovered in 2023 using the imaging method.
Is WISE J033605.05-014350.4 b in the Habitable Zone?
The position of WISE J033605.05-014350.4 b relative to the habitable zone of WISE J033605.05-014350.4 cannot be precisely determined from the available orbital data.
Temperature on WISE J033605.05-014350.4 b
The equilibrium temperature of WISE J033605.05-014350.4 b is about 325 K (52 °C) — in a range broadly comparable to Earth, whose equilibrium temperature is 255 K. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
A year on WISE J033605.05-014350.4 b — one full orbit around WISE J033605.05-014350.4 — lasts 2,560.0 Earth days, longer than an Earth year. It orbits at an average distance of 0.970 AU — comparable to the inner Solar System.
How Was WISE J033605.05-014350.4 b Discovered?
WISE J033605.05-014350.4 b was discovered in 2023 using the imaging method, with observations from James Webb Space Telescope (JWST).
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.
