The Sun is the star at the center of our solar system and is responsible for the Earth’s climate and weather. It is an almost perfect sphere with a difference of just 10km in diameter between the poles and the equator. The average radius of the Sun is 695,508 km (109.2 x that of the Earth) of which 20–25% is the core. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest particles of debris in its orbit. Electric currents in the Sun generate a magnetic field that is carried out through the solar system by the solar wind. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and aurorae. There are billions of stars like our Sun scattered across the Milky Way Galaxy. Today we have prepared 10 awesome facts about the Sun that will arouse your curiosity.
1. Does the Sun Have a Twin?
The Sun is 400x larger than the Moon and 400x further away from Earth making them look to be the same size.
2. Is our Sun Middle-Aged?
The Sun is 4,5 billion years old and will continue for 5 billion more years before it uses all of its hydrogen.
3. The Sun is Well Protected!
The atmosphere of the Sun has three layers: the photosphere, the chromosphere and solar corona.
4. Solar Eclipse: Limited Window.
Solar eclipse can only last at least 7 minutes and 58 seconds because the Sun moves very quickly.
5. The Most Massive.
The Sun is the center of our solar system and makes up 99.8 percent of the mass of the entire solar system.
6. The Biggest.
If the Sun were as tall as a typical front door, Earth would be about the size of a nickel.
7. Energy For Life .
Without the Sun’s intense energy, there would be no life on Earth.
8. The Only sun that gives life.
The Sun is one of more 100 billion stars in the Milky Way, but the only known star to host a solar system with life.
9. The Sun is far away, but it is very hot.
Only half of one-billionth of the energy released by the Sun reaches Earth.
10. The Sun is da Bomb.
The Sun creates so much energy that every second its core releases 100 billion nuclear bombs.
