2MASS J12073346-3932539 is a small, cool red dwarf of spectral type M8, lying 210 light-years away. Its mass is 0.188 solar masses, its radius is 0.219 solar radii, and its surface temperature is 2830 K, all of which fall below the Sun's corresponding values.
One planet is known to orbit this star: 2MASS J12073346-3932539 b. It was discovered in 2004 by direct imaging and is classified as Jupiter-like, meaning its radius exceeds four times Earth's. Its reported mass is 1650 Earth masses, roughly 5.2 times Jupiter's mass, and its radius is 15.7 Earth radii, larger than Earth's. Its mean density is 2.36 g/cm³, 0.428 times Earth's. No orbital period is reported for this planet.
