Learning Objectives By the end of this lesson you should… Be able to recall and recognise the relative positions of the Earth, Sun and planets Be able to recall the relative nature and sizes of planets, stars, comets, meteors, galaxies and black holes Be able to state the components of the known Universe Be able to explain the term ‘light year’ What is a light year? The distance light will travel in one year Calculate how far this is in metres! 300 000 000 x 60 x 60 x 24 x 365.25 9.46728 x 1015 m

Where would it be on your scale?

The Solar System… a quick quiz What planet are we on? Which planet(s) are between us and the sun? Which is the smallest planet? Which is the largest planet? Which planets have moons? Which planets have rings? Where is the asteroid belt? What is the nearest star to Earth?
