2M0437 b, or 2MASS J04372171+2651014 b, is an extrasolar planet that orbits the red dwarf of the pre-main sequence 2MASS J04372171+2651014, 418 light-years away in the constellation of Taurus. It is a gas giant, with a mass 4 times that of Jupiter. It is one of the few exoplanets directly imaged. The planet is of importance to astronomers as it challenges models of planet formation by nucleus accretion and disk instability.[3][4]
