The gas gauge sensor is most likely stuck. It is inside of the tank and over time it will get corroded.
fuel gage sender unit is faulty
A short in a wire or a failure of gauge or sender.
The fuel sensor in the gas tank is bad and needs replaced.

Youre fuel level sensor might be broken near the top of its stroke (inside tank).
The closest ones would be 15/16" and 1". I suggest 1" because its more common and there would be a wider selection of jewelry.
The problem is most likely the sending unit, not the gauge itself. The sending unit would have to be replaced.
It would crash on Saturn.
Saturn has a solid surface so if you land on Saturn you would sink into hotter and deeper surface so you would die.
