2MASS J22362452+4751425 b
2MASS J22362452+4751425 b is a cold gas giant orbiting the K7 V star 2MASS J22362452+4751425 in the constellation Lacerta. It lies about 227 light-years from Earth and was discovered in 2016 using the imaging method.
Is 2MASS J22362452+4751425 b in the Habitable Zone?
The position of 2MASS J22362452+4751425 b relative to the habitable zone of 2MASS J22362452+4751425 cannot be precisely determined from the available orbital data.
Orbit and Year Length
2MASS J22362452+4751425 b orbits at an average distance of 230.000 AU.
How Was 2MASS J22362452+4751425 b Discovered?
2MASS J22362452+4751425 b was discovered in 2016 using the imaging method, with observations from W. M. Keck 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 2MASS J22362452+4751425 b?
2MASS J22362452+4751425 b is 226.9 light-years (69.6 parsecs) from Earth. Light arriving here tonight left the planet around the year 1800. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 3,993,440 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. 2MASS J22362452+4751425 b scores 0.07, ranking #4,882 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
