What are the layers of the Sun in order?
The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region.
What happens in the 3 layers of the Sun?
The Sun’s atmosphere also has three layers: the photosphere, the chromosphere, and the corona. Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun. Some features of the Sun’s surface include sunspots, solar flares, and prominences.
How hot is each layer of the Sun?
The centre of the Sun: about 15 million kelvin (K). Radiative Zone: Temperature falls from about 7 million to about 2 million K across this zone. Convection Zone: drops from 2 million K to 5800K in this zone. Photosphere: about 5800K, although sunspots are about 3800 K – that’s why they are dark.
Did you know facts about the Sun?
Facts about the Sun
- The Sun accounts for 99.86% of the mass in the solar system.
- Over one million Earth’s could fit inside the Sun.
- One day the Sun will consume the Earth.
- The energy created by the Sun’s core is nuclear fusion.
- The Sun is almost a perfect sphere.
- The Sun is travelling at 220 km per second.
What layer of the Sun is the hottest?
Core. The hottest part of the Sun is the core, at 28,080,000°F, on average.
How thick is each layer of the Sun?
| Core | Radius of 150,000 km | 10,000,000 K |
|---|---|---|
| Convective Zone | 200,000 km thick | 500,000 K |
| Photosphere | 500 km thick | 5800 K |
| Chromosphere | 10,000 km thick | 4,000 to 400,000 K |
| Corona | 5,000,000 km thick | 1,000,000 K |

What are 10 fun facts about the sun?
Here are more fun facts about the sun, provided by the NASA Science Space Place:
- The sun is a star.
- The sun is the closest star to our planet, which is why we see the sun so big and bright.
- The Earth orbits around the sun.
- The sun is way bigger than the Earth.

What are 5 interesting facts about the sun?
Which layer of the sun is the thinnest?
chromosphere
Compared to the radius of the Sun, which is nearly 700 thousand kilometers (more than 400 thousand miles), the chromosphere is a very thin layer.
How are the layers of the sun divided?
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. There are four outer layers of the Sun, and the Corona is the outermost one.
Which is the thickest layer of the Sun?
The convection zone is a thick layer starting at around 70% from the sun’s radius that gets mixed with the outer surface at the other end (the photosphere). It forms the atmosphere of the sun. The sun’s energy radiates up from the sun’s interior out to these outer layers, which we see as sunlight.
How many pages are in layers of the Sun?
See the fact file below for more information on the layers of the Sun or alternatively, you can download our 22-page Layers of the Sun worksheet pack to utilise within the classroom or home environment. The Sun is a star at the center of the Solar System.
Which is part of the sun can be seen from Earth?
There are some regions in the Sun which can be seen from the Earth and those visible regions of the Sun are part of its atmosphere. Being a ball of hot burning gases, the Sun is composed of several parts: the corona, chromosphere, photosphere, core, Sunspots and prominences. Corona is the outermost layer of the Sun’s atmosphere.
