I am learning about the core of the Earth. What is inside our planet, Earth? The core is in the center of the Earth. The outer core is a barrier to the inner core. The mantle is a very hot layer of magma. There are also the earths plates. If the plates start to move, they will start to move again, but if they do move, the plates can cause an earthquake. That is what is Inside our planet, Earth.

The Solar System. Neptune is 17 times bigger than Earth. Neptune is named after the king of water. Neptunes orbit is 165 Earth days. Neptunes day is 19 Earth hours. Pluto is the smallest planet.
