Is 2MASS J11550485-7919108 b in the Habitable Zone?

The position of 2MASS J11550485-7919108 b relative to the habitable zone of 2MASS J11550485-7919108 cannot be precisely determined from the available orbital data.

Temperature on 2MASS J11550485-7919108 b

The equilibrium temperature of 2MASS J11550485-7919108 b is about 2,506 K (2,233 °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 J11550485-7919108 b orbits at an average distance of 587.000 AU.

How Was 2MASS J11550485-7919108 b Discovered?

2MASS J11550485-7919108 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 J11550485-7919108 b?

2MASS J11550485-7919108 b is 329.0 light-years (100.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1697. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 5,790,400 years to make the journey.
