   The Sun, like other stars, is a huge spherical object made of hydrogen and helium. Its diameter reaches 1.400.000 km, or 109 times the Earth’s diameter; but is 4 times less dense than the Earth due to its composition. The Sun is not only made of the glowing gas that we see with a telescope. It has, exactly

   How far is the Earth from the Sun?

   • The Earth’s is the one we’re most familiar with: with a mean distance from the Sun of 150 million kilometers (or 93 million miles). But this distance, the Earth-Sun distance, is only a little more than 100 times the size of the Sun itself, which is only a little more than 100 times the size of the Earth itself.

   How big is the Sun?

   • We know that the sun has a diameter of 864,000 miles. Multiplying this number by pi will give the sun’s circumference: 2,713,406 miles. Another way to appreciate the size of the Sun is by calculating the time it would take to travel around it using different means of transportation. Yes, we are that geeky!
