    • Topic 1: Visible light and The Solar System
      • P1.1 The Solar System
        • Structure
          • The geocentric model: The sun, moon, planets, and stars ie everything, all orbited the Earth in a series of concentric circles.
            • This model originates from ancient Greek civilisation 2000-2500 years ago and lasted for 1500-2000 years.
          • The heliocentric model: The Earth and other planets orbited our sun -then considered as the centre of our universe.
            • Copernicus published his heliocentric theory and calculations in 1543, just in time, two months before his death!
          •    Our contemporary model: The 8 major planets, minor planets and asteroids orbit the Sun in slightly elliptical orbits (our 'Solar System'), but our Sun is just one of millions-billions of stars in our galaxy (we see part of it as the 'Milky Way') and in turn the observable universe itself contains billions of other galaxies.
        • Telescopes
          • The telescope was invented at the end of the 16th century. It allowed scientists to see objects in space in much greater detail than with the naked eye and to fin new objects.
