There is a display of Christmas trees at Caldbeck church this weekend. I loved this Solar System design. What a brilliant idea! The star at the top of the tree is our Sun and the planets spiral round the tree in order. You can easily identify the Earth and red Mars along with Saturn in the pictures. I wasn't able to go myself so I don't know how they dealt with Pluto, which was relegated from full planet status some years ago. It spoils the mnemonic I used to use with classes: My Very Easy Method Just Speeds Up Naming Planets.
