This is because the Earth travels on an elliptical orbit around the Sun. The distance between the two bodies varies from 147 to 152 million kilometres. The Sun is middle-aged. At around 4.6 billion years old, the Sun has already burned off about half of its store of Hydrogen. It has en...
The sun was born about 4.6 billion years ago. Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. As the nebula collapsed because of its gravity, it spun faster and flattened into a disk. Most o...

What is the Sun? How Hot is the Sun? Facts About the Sun Lesson Summary Frequently Asked Questions What is the temperature of the outer surface of the sun? The photosphere is the layer of the Sun that we see when we observe it from the Earth. It can be considered the Sun's "surf...
6. The Sun has layers The Sun looks like a burning ball of fire, but it actually has an internal structure. The visible surface we can see is called the photosphere, and heats up to a temperature of about 6,000 degrees Kelvin. Beneath that is the convective zone, where heat moves slo...
Most people already know the basic facts about the sun. It's a star. It's massive. And it is considered the center of the solar system galaxy. However, the sun is much more than just the gravitational center of our galaxy. In truth, it is the center of life for our world. Every ...
Interesting facts about the sun The sun has 3 inner layers Core Radiative Zone (innermost layer of nuclear fusion) Convective Zone (where the heat moves slowly from the inner layer to the surface) Outer layers of the sun Photosphere
2. How Old is the Sun? Scientists estimate the Sun is about 4.6 billion years old, or approximately halfway through its life cycle. The Sun will continue to live on the hydrogen in its center for a few billion more years with its temperature and size staying about the same—so, no sur...
One of the most misunderstood things about the Sun is why planets are even in orbit of it in the first place. And it can be difficult to understand. The short answer is “gravity”, but this doesn’t really explain why they’re orbiting the Sun and not being pulled into it. ...
Parker Solar Probe has kissed the sun, and now its telling us everything. In just one short year, the probe’s initial observations have already unraveled decades-long mysteries about our home star. The probe has revealed insight into the formation and structure of solar winds, the connection...
