The Sun's Name Means:

The Romans called the sun Sol, which in English means sun. In ancient Greece, the sun was called Helios.

Our Sun is not unique in the universe. It is a common middle-sized yellow star which scientists have named Sol, after the ancient Roman name. This is why our system of planets is called the Solar System. There are trillions of other stars in the universe just like it. Many of these stars have their own systems of planets, moons, asteroids, and comets.

What is the sun?

  • The Sun gives life to the Earth and the Earth would have no life at all without the energy it receives from the Sun.
  • The Sun is only one of millions and millions of stars in the Galaxy.
  • We see it as a large round red ball only because we are much closer to the Sun than to any of the other stars.
  • Other stars may be larger, brighter, smaller or fainter than our Sun but they are so very far away that we only see them as points of light in the night sky.
  • The Earth is one of nine planets that orbit round the Sun in what we call the Solar System.
  • Solar is the adjective from Sun and comes from the Latin word for Sun – sol, which also gives us the French soleil. (and the word for Sun in several mother European languages).
  • The Sun measures 2,715,395 miles (4.730,005 kilometres) right round (circumference).
  • The Sun is 92.96 million miles or 149.6 million kilometres from the Earth.
  • The Sun is bigger than can really be imagined, over one million times bigger than the Earth.
  • This measurement is taken as one Astronomical Unit and is how we measure distances in our Solar System
  • Like all stars, the Sun is composed of a great burning ball of gases. It is made of 92.1% hydrogen and 7.8% helium (helium is from the ancient Greek word helios, which means Sun).
