AB Pictoris b is a planet (or possible brown dwarf), orbiting the star AB Pictoris. The estimated Mass of this planet is 13.5 ± 0.5 Jupiter masses (MJ). However, it is actually unknown what the true mass of it is, due to it's young age. Certain models predict the planets mass to be around 11 Jupiter masses, but some predict it to be as high as 70 Jupiter masses. However, using evolutionary models, it comes up to around 13 Jupiter masses.

As the actual mass is not known and isn't known if the mass of the objects exceeds the deuterium burning limit, it is not clear whether or not the planet should be identified as a extrasolar planet or brown dwarf.

The surface temperature of the planet, as it orbits close to it's host star, is estimated to be around 1600 K - 2400 K (1326 °C, 2420 °F) - (2126 °C, 3860 °F), though the actual surface temperature is unknown.
