Have you ever wondered what planets' interiors contain? Let's quickly travel to each world's centre
Terrestrial planets include Earth, Mars, Venus, and Mercury. They have a solid crust, a rocky mantle, and a dense metal core
Mercury: The majority of Mercury's volume is composed of iron and nickel. In contrast, its mantle and crust are thin
Venus: It has an iron-nickel core, but its core proportion is slightly smaller. The core is encircled by a thick rocky mantle and crust
Earth: Iron and nickel make up the solid inner core of the Earth, while the outer core is liquid. Our magnetic field is produced by the moving liquid core
Mars: It is composed of a silicate mantle, a rocky crust, and a molten iron-sulfide core. Compared to Earth, its core is smaller and colder
Jupiter and Saturn: they have dense cores (rock, metal, ice), but most of their mass is liquid hydrogen and helium. Their atmospheres blend smoothly into their interiors
Uranus and Neptune: 1 with thick layers of water, ammonia, and methane ices, and thinner hydrogen-helium atmospheres
Every planet is made up of layers, whether they are rocky mantles, metallic cores, icy shells, or swirling gases. Each layer is distinct but is influenced by gravity and chemistry
