Re: APOD: A Jupiter Vista from Juno (2020 Nov 23)
What kind of density does metallic hydrogen have? I've looked but can't seem to find either a measured or calculated value. Seems it would have to be denser than liquid water.

Re: APOD: A Jupiter Vista from Juno (2020 Nov 23)
Thanks. I still don't quite get it. The higher the pressure, the more likely a material is to be liquid than gas. Likewise, the lower the temperature, the more likely liquid than gas. Compared to Earth, Jupiter is both colder (a lot colder) and the pressure is far higher, so it seems it ought to be ...

Question: Jupiter is considered a "gas giant," but its density is ~ 1.3 g/cm^3, or about 30% denser than liquid water. If it were a liquid giant, that's what its density would be, so...why is it a gas giant? I'm sure there's a good reason, but it beats me.
