In deserts here on Earth, heat that has travelled 150 million km from the Sun can be hot enough to fry an egg. The Sun’s surface is a super-hot 6,000°C, and its centre or core is even hotter.
Amazing! The Sun is a star – a gigantic ball of burning gas. It has been shining for about five billion years.
Why must you never look at the Sun?
Not even sunglasses fully protect your eyes from the Sun’s dangerous ultraviolet (UV) rays. UV can burn your eyes and make you blind. If you want to see the Sun safely, ask an adult to show you how to project its image on to a sheet of paper.
Is it true? The Sun has spots.
Yes. The Sun is not the same colour all over. Some areas of its surface are darker. These spots are little pockets that are slightly cooler. Of course, sunspots are only ‘little’ compared to the Sun – some grow to be as large as Jupiter, the biggest planet in the Solar System!
When does the Sun go out?
When there’s a total eclipse. This happens when the Moon’s path takes it between the Earth and the Sun, and the Moon casts a shadow across the surface of the Earth.
