2MASS J02192210-3925225 b
2MASS J02192210-3925225 b is a cold gas giant orbiting the M6 star 2MASS J02192210-3925225 in the constellation Phoenix. It lies about 131 light-years from Earth and was discovered in 2015 using the imaging method.
How Big Is 2MASS J02192210-3925225 b?
2MASS J02192210-3925225 b has a radius of 16.14 times that of Earth, or 1.44 times the radius of Jupiter. Its mass is 4,418 times that of Earth.
Is 2MASS J02192210-3925225 b in the Habitable Zone?
2MASS J02192210-3925225 b orbits beyond the outer edge of the habitable zone of 2MASS J02192210-3925225. At that distance, any surface water would almost certainly be frozen.
Habitable zone of 2MASS J02192210-3925225: 0.063–0.167 AU (conservative: 0.080–0.158 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
2MASS J02192210-3925225 b orbits at an average distance of 156.000 AU.
How Was 2MASS J02192210-3925225 b Discovered?
2MASS J02192210-3925225 b was discovered in 2015 using the imaging method, with observations from Cerro Tololo Inter-American 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 J02192210-3925225 b?
2MASS J02192210-3925225 b is 130.8 light-years (40.1 parsecs) from Earth. Light arriving here tonight left the planet around the year 1896. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 2,302,080 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 J02192210-3925225 b scores 0.06, ranking #5,209 of 5,565 planets with a known ESI. For reference, Mars scores about 0.70.
