2MASS J02192210-3925225 b: A Young Star and Its Giant Planet
2MASS J02192210-3925225 is an M6 star - a small, cool red dwarf - with one known planet. Its mass is 0.108 solar masses and its radius is 0.281 solar radii. The star is 0.035 billion years old, placing it in a very young age class, and its temperature is 3060 K. As an M-type star, it is cooler and redder than the Sun.
The single planet orbiting this star is 2MASS J02192210-3925225 b, discovered in 2015 by imaging. It is a Jupiter-like planet, a size class that describes radius rather than composition, and its measurements give it a radius of 16.1 Earth radii and a mass of 4420 Earth masses. Its mean density is 5.79 g/cm³. No orbital period is reported for 2MASS J02192210-3925225 b.
