2MASS J21252752-8138278 b
2MASS J21252752-8138278 b is a hot Jupiter orbiting 2MASS J21252752-8138278 in the constellation Octans. It lies about 111 light-years from Earth and was discovered in 2024 using the imaging method.
Is 2MASS J21252752-8138278 b in the Habitable Zone?
The position of 2MASS J21252752-8138278 b relative to the habitable zone of 2MASS J21252752-8138278 cannot be precisely determined from the available orbital data.
Temperature on 2MASS J21252752-8138278 b
The equilibrium temperature of 2MASS J21252752-8138278 b is about 1,616 K (1,343 °C) — hot enough to melt many metals. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
2MASS J21252752-8138278 b orbits at an average distance of 7,493.000 AU.
How Was 2MASS J21252752-8138278 b Discovered?
2MASS J21252752-8138278 b was discovered in 2024 using the imaging method, with observations from European Space Agency (ESA) Gaia Satellite.
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 2MASS J21252752-8138278 b?
2MASS J21252752-8138278 b is 111.3 light-years (34.1 parsecs) from Earth. Light arriving here tonight left the planet around the year 1915. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 1,958,880 years to make the journey.
