Feb 3, 2024 · The four layers of the Sun are the core, radiative zone, convective zone, and atmosphere. The Sun is a colossal nuclear reactor at the heart of our solar system. Our favorite star is about 109 times the diameter of Earth and over 330,000 times its mass.
Oct 10, 2012 · This graphic shows a model of the layers of the Sun, with approximate mileage ranges for each layer: for the inner layers, the mileage is from the sun’s core; for the outer layers, the mileage is from the sun’s surface. The inner layers are the Core, Radiative Zone and Convection Zone.

Temperature: 6500 Kelvin at the bottom to 4000 Kelvin at the top Density: 2 × 10−4 kg/m3 It is the deepest layer of the solar atmosphere that we usually see from earth covering a distance of about 400 km from the center of the solar disk. Due to its low density, it is relatively transparent, resulting in the photosphere being regarded as the visual...
Temperature: 4000 Kelvin at the bottom to 8000 Kelvin at the top Density: 5 × 10−6 kg/m3 It is found above the photosphere at a distance between 400 km to 2100 km above the solar surface. The temperature of chromosphere gets hotter as we go further away from the sun. Due to its high temperature hydrogen emits light that gives off a reddish color, k...
Temperature: 8000 Kelvin at the bottom to 500,000 Kelvin at the top Density: 2 × 10−10 kg/m3 A narrow region covering a thickness of about 100 km between the chromosphere and the next adjacent layer called the corona. The temperature in this region is also found to increase sharply as we move further away from the core and hence the name transition...
Temperature: 500,000 Kelvin at the bottom to 1,000,000 Kelvin at the top Density: 10−12 kg/m3 It is the outermost layer of the sun’s atmosphere that we normally see during a total solar eclipse. It starts at about 2100 km above the photosphere and has no upper limit as it merges with the sun’s outer atmosphere. It is the hottest part of the solar a...
The layers of the Sun are divided into two larger groups, the outer and the inner layers. The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the Convection Zone.
- Core: The Inner Layer. The heat from the core is 15 million degrees Kelvin which translates to roughly 27 million degrees Fahrenheit. Kelvin is a temperature scale that picks up where the Celsius degree ends.
- The Radiation Zone. The radiation zone is just outside the core. The function of this layer is to transfer energy from the core to the other layers. The temperature at this layer is cooler than the core at 7 million degrees Fahrenheit causing thermal radiation.
- The Convection Zone. The convection zone is not dense enough to transmit energy. Instead, this layer moves heat to the surface of the sun where it cools and drops back into the convection zone where it reheats.
- Photosphere Gives the Sun Color. The photosphere is the layer that can be seen from the Earth. The temperature of the photosphere is about 10 million degrees Fahrenheit.
The heliosphere extends beyond the orbit of the planets in our solar system. Thus, Earth exists inside the Sun’s atmosphere. Outside the heliosphere is interstellar space. The core is the hottest part of the Sun. Nuclear reactions here – where hydrogen is fused to form helium – power the Sun’s heat and light.
Apr 11, 2022 · The Sun, our star, has several layers beneath the visible surface: the core, radiative zone, and convective zone. These, in turn, are surrounded by a number of layers that make up the solar atmosphere.
