1 My Project is about….

2 Introduction The Sun is one out of billions of stars, it is the closest star to Earth. The Sun rotates once every 27 days, it is now a middle- aged star. The Sun formed over four and a half billion years ago (according to scientists). You may think the Sun will die soon, but it will keep shining for at least another five billion years. The Sun is one out of billions of stars, it is the closest star to Earth. The Sun rotates once every 27 days, it is now a middle- aged star. The Sun formed over four and a half billion years ago (according to scientists). You may think the Sun will die soon, but it will keep shining for at least another five billion years.

3 What is the Sun made up of? The Sun is mostly hydrogen and helium The Sun is mostly hydrogen and helium If you could take apart the Sun and pile up its different elements, you’d find that 74% of its mass comes from hydrogen. with 24% helium. The remaining 2% is includes trace amounts of iron, nickel, oxygen, and all the other elements we have in the Solar System. In other words, the Solar System is mostly made of hydrogen.

4 Size The Sun’s diameter is about 870,000 miles wide. It is 109 times wider than Earth, and is 333,000 times heavier. Over one million Earths could fit inside the Sun. You could flatten out 11,990 Earths to cover the surface of the Sun The Sun is about 1,989,000,000,000,000,000,000,000,000,0 00 kilograms!

8 Temperature The Sun’s surface is called the photosphere. The temperature of the photosphere is about 10,000° Fahrenheit (5537.7 degrees Celsius). The temperature at the core, of the Sun, is about 27 million° Fahrenheit (15 million degrees Celsius). That’s pretty hot! The Sun’s surface is called the photosphere.

11 What would happen if we didn’t have the Sun? Without the Sun, Earth could not support life. The Sun gives off heat and light that the Earth needs to support life. Without the Sun, Earth could not support life. The Sun gives off heat and light that the Earth needs to support life.

12 How far away is the Sun? If you could take a journey in an normal airliner flying at its normal speed (about 644 km an hour) travelling from Earth to the Sun, it would take 20 years to reach your destination, and that's without stopping.

13 Facts The official definition of a star like The Sun is a "Yellow G2 Dwarf." The official definition of a star like The Sun is a "Yellow G2 Dwarf." Light from the Sun takes 8 minutes to reach Earth, 40 minutes to reach Jupiter and 7 hours to reach the edge of the Solar System. Light from the Sun takes 8 minutes to reach Earth, 40 minutes to reach Jupiter and 7 hours to reach the edge of the Solar System. In the same way that the planets orbit around the Sun, the Sun orbits around the centre of the Milky Way galaxy, taking 225,000,000 years to complete a full orbit, travelling at 800,000 kilometres per hour.
