Because "solid surface" isn't a requirement to be considered a planet. The current classification is as follows: (1) A "planet"1 is a celestial body that: (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic …

The Short Answer

Because "solid surface" isn't a requirement to be considered a planet. The current classification is as follows: (1) A "planet"1 is a celestial body that: (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit. Jupiter easily suffices. It's also fair to say it is more complex than simply a 'big ball of gas,' while there is no discrete boundary where air becomes 'ground' you would instead gradually transition to more solid resistance as you descended.
