I assumed gravity would be more than 14% of the gravity on Earth but just found out the size of Neptune is a lot smaller than I had imagined. It's only 4 times the diameter of Earth, while Jupiter is 1,300 times the diameter of Earth. I didn't realize the size difference between the two were so far off.

To be fair jupiter is 99% of the mass in the solar system (that isnt the sun).

The sun is 99.8% of the mass of the entire system

Of the rest of the .15-.2% of the mass left, Jupiter is like 2.5x bigger than the rest of the stuff combined.

Jupiter is really big. So if the sun.
