What does it mean when it is said that a planet is made of gas?

Like, how is that possible? Is actual gas? Can I get to the other side of it just going through it? And more importantly, how the hell does all of that mass stay together if it’s gas? Wasn’t is supposed to just spread and try to occupy the maximum volume possible?

The planet *is* made of gas, usually heavier gases with a very small, very dense metal core to produce the amount of gravity needed to hold everything together. You could theoretically go through it, just not straight through the center. Think of it as a planet that’s mostly atmosphere instead of mostly rock and dirt and stuff
