Obviously a lot of you would have known about this, but still; ‘Dramatic title!’
Anyway, I was browsing a website which hosted a bunch of astronomical ‘facts’ and one these so called facts stated: “Jupiter, Saturn, Uranus and Neptune are made up of just gas with no solid surface to land on.” And considering how wrong this is it annoyed me. so I decided to make this post…
So what is contrary to common knowledge about the Gas Giants?
- For starters, Neptune and Uranus are commonly not even classed as gas giants any more! instead they are called Ice Giants due to their differences in both chemical composition and physical state compared to traditional Jovian planets.
Even regular gas giants are barely that. Their name deceives them for they only consist of roughly 2-10% gas on the surface. The huge pressure of the gas forces hydrogen and helium into a liquid state beneath the surface, and even further down it becomes what is known as ‘Metallic Hydrogen’ before you reach the core which is, probably, just rock and ice.
