Jupiter freaks me out. It is huge, big enough to greatly affect the path of any smaller body that is unfortunate enough to cross its path, with potentially adversarial results for Earth. Even more so is its composition. Should you be unfortunate enough to find yourself on a ship heading towards where the surface of Jupiter, you’d have to pass through liquid hydrogen and then would hit metallic hydrogen. While this may seem normal enough, these two layers seem so alien to me when compared with the chemical diversity of Earth’s surface. It is quite fascinating to me the huge difference in composition that a relatively small (on a universal scale) difference in distance from the sun can have on the composition of a planet. Even better is that I know how it happened, thanks to the Nebular Formation theory, and still can’t help but marvel at the diversity of planetary composition between the Terrestrial and Jovian planets.
