The distance of Earth from the Sun is about 108 times the diameter of the Sun. Likewise, the distance between the Earth and the Moon is also about 108 times the diameter of the Moon.
Viganella, a city in Italy where the sun doesn’t rise for three months a year, has a mirror located on a mountain to reflect the sunlight.
A new telescope built to study the Sun has released its first images. They show the surface of the Sun in the most exquisite detail we’ve ever seen – revealing convection granules the size of Texas, and tiny magnetic features – the roots of fields that extend far into space.
In an unbelievable coincidence, the moon is exactly four hundred times smaller than the Sun but four hundred times closer to the Earth, so that both the Sun and the Moon appear to be precisely the same size in the sky – which gives us the phenomenon we call a total eclipse.
Even though the sun won’t die for another 5 billion years, humans only have about 1 billion years left on Earth because the sun will change and become hot enough to boil and evaporate our oceans.
There is a star in our galaxy that is 5 billion times volume of our sun.
Every second of every day, the sun converts 700 million tons of hydrogen into 695 million tons of helium. The other 5 million tons becomes energy. Every second.
The largest known star is 4,982,686,912 times bigger than the sun, and is only 9,500 light-years away. If placed at the center of the Solar System, its photosphere would engulf the orbit of Jupiter, although the radius is not known for certain and may be larger than the orbit of Saturn.
The sun’s core is so hot that a piece of it the size of a pinhead would give off enough heat to kill a person 100 miles away.
