The video shows a 3D model of a planet, which is rotating slowly. The planet is composed of several layers, with the outermost layer being a brown crust, followed by a layer of grey rock, and then a layer of black material. The innermost layer is a bright white sphere, representing the core of the planet. The model is set against a black background, with small white dots scattered around, simulating stars in space. The rotation of the planet is smooth and continuous, allowing for a clear view of all layers.
