The word 'sun' is believed to be derived from the Old English word 'sunne'. |
The sun is responsible for the weather and the climate on earth. |
The sun's radius is approximately 695,508 km. This is equal to 109.2 times the earth's radius. |
The circumference at the sun's equator is 4,370.005.6 km. |
The sun weighs 1,989,100,000,000,000,000,000 kg. This is equal to 333,060 times earth's mass. |
The sun has a surface area that is 11,990 times that of the earth. |
The temperature on the surface of the sun is 5500 degrees Celsius. The internal core temperature is believed to reach 15 million degrees Celsius. |
The sun's heat at its core is driven by nuclear reactions. |
The sun takes up to 250 million years to orbit the Milky Way's center. |
The sun travels at a speed of 220km each second. |
If it were possible, you could fit 1 million planet earths inside the sun. It is believed that one day the sun will consume Mercury, Venus and the earth. |

There are more than 100 billion stars in the Milky Way and the sun is only one of these. |
The solar activity of the sun can cause changes and disruptions in radio communication on earth, as well as to electric power. |
It is believed that magnetic instabilities on the sun may be responsible for ice ages on earth. |
The surface temperature on the sun is increasing and eventually it will be so hot on earth that our water will evaporate (not for about another one billion years). |
