Section illustrating the interior structure of the sun.Specifications The model is of 1:400000000 ratios, with the diameter of 34.5 era. Basic parameters: Equatorial radius: 696,000 KM; Quality: 332,946 times of the Earth's; Gravity: 27.9 times of the Earth's; Rotation cycle: 25.38 (Earth day); Wong Check Inclination: 7.25 degrees.StructureThe model shows both the surface and internal structure.The surface contains corona, prominence, chromospheres layer and the sunspot group. The internal contains otosphere, troposphere, radiatinglayer and nucleus. The colors of both surface and internal show the different temperatures.Coronal ball is outside of chromospheres layer, with its area of several times of the diameter of chromospheres layer. There is no dear boundary between, please be aware that it is showed partly only.
