Capturing the Sun
You do not have to worry about capturing the sunset of Oia today as you still have 4.5 billion years ahead!
• The Sun is 4.65 billion years old and it is estimated that it will still live as much.
• The energy emitted by the Sun in one second covers Europe's energy needs for 13 million years.
• With the cheapest electricity invoice, the energy that the Sun transmits in space in one second would have a value equal to the budget of Greece for 10,000 trillion years.
• If we shrank the Sun in the size of an orange, the Earth would be at a distance of 15m having the size of a sesame seed, while the next star, Proxima Centauri (or Alpha Centauri C), would be 4,000 km away.
• The Earth - Sun distance is called Astronomical Unit and is equal to 149,600,000 km.
• If we had to walk from Earth to the Sun, we would need 2,123 years.
• If we used a car that would travel non-stop at 100 km / h, we would need 170 years.
• An airplane that flies at 800 km / h would cover the same distance in 21 years.
• Yet, a ray of light only takes 8 minutes and 20 seconds to cover the same distance.
• Greek philosopher, mathematician and astronomer Thales of Miletus was the first person to predict a total solar eclipse in 585 BC.
• During a total solar eclipse, the moon's shadow on Earth has a diameter of 270 km and runs at a speed of 1,675 km / h.
• The first photo of the Sun (daguerreotype) was taken in 1842. So, keep on travelling!
