2MASS J22501512+2325342 b is a exoplanet orbiting the M3 star 2MASS J22501512+2325342 in the constellation Pegasus. It lies about 187 light-years from Earth and was discovered in 2018 using the imaging method.
Is 2MASS J22501512+2325342 b in the Habitable Zone?
The position of 2MASS J22501512+2325342 b relative to the habitable zone of 2MASS J22501512+2325342 cannot be precisely determined from the available orbital data.
Temperature on 2MASS J22501512+2325342 b
The equilibrium temperature of 2MASS J22501512+2325342 b is about 1,600 K (1,327 °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 J22501512+2325342 b orbits at an average distance of 518.000 AU.
How Was 2MASS J22501512+2325342 b Discovered?
2MASS J22501512+2325342 b was discovered in 2018 using the imaging method, with observations from The 2 (Two) Micron All Sky Survey (2MASS).
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 J22501512+2325342 b?
2MASS J22501512+2325342 b is 186.7 light-years (57.2 parsecs) from Earth. Light arriving here tonight left the planet around the year 1840. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 3,285,920 years to make the journey.
