Do you know a mnemonic for remembering the planets in order… could you invent one….? …Make it as memorable as you can!

What’s the most interesting fact you know about one of the planets?

Planet data Planets can be classed different ways… Think of 3 different ways of classifying planets. What criteria are you applying?

Composition ROCKY PLANETS (Mercury - Venus - Earth - Mars - Pluto) The rocky planets are mostly made up of rock and metal. These planets are very heavy and move slowly. They also do not have rings and very few moons. GAS PLANETS (Jupiter - Saturn - Uranus - Neptune) The gas planets are mostly made up of gases (hydrogen and helium). These planets are light for their sizes (just like a big air balloon) and move quickly. They have rings and lots of moons.

Size SMALL PLANETS (Mercury - Venus - Earth - Mars - Pluto) The small planets have diameters less than 13000 km across. Mercury and Pluto are sometimes referred to as lesser planets because they are so tiny. GIANT PLANETS (Jupiter - Saturn - Uranus - Neptune) The giant planets have diameters greater than 48000 km. The giant planets are sometimes also referred to as gas giants.

Which planets can we see from the Earth? What do you think effects if we can see a Planet from the earth? The size of a planet How far away it is The planets surface Mercury, Venus, Mars, Jupiter and Saturn

Questions Please answer the following questions in FULL sentences in your book In your books write down A-F and say what they are. What makes up what can be found at F? Which two planets have rings? Which planet has a longer day than its year? Even though planet B is closer to the Sun, C is hotter, can you explain why?
