I calculate that if it were a star it would be about 42, but because of the strange and special way they calculate absolute magnitude for planets, it is 11. Stellar absolute magnitudes are the apparent magnitude at an assumed distance of 10 parsecs, which is 2,062,650 AU, but planetary absolute magnitudes are at an assumed distance of 1 UA. To convert from stellar absolute magnitude to planetary magnitude, subtract 31.57. See the source. Pluto's apparent magnitude is about 14 and its distance is about 40 AU.
