WHAAAAT!!

There's no mention of mass. Gravity could actually be 5.76 times lower* than that on Earth, if mass was exactly the same, which granted, is not likely. Anyway without knowing the mass there's absolutely no way to tell the gravity.

* Remember that gravity is proportional to the product of the two masses and inversely proportional to the square of the distance.

Regarding Jupiter: its mass is 318 times the Earth, but it's radius is ~11 times bigger, that's why its surface gravity is ~2.5 times bigger. 318/11^2 = 2.6 <-- Math is not compltely correct since I rounded up too many numbers, but you get the idea.
