This Planets in Order Poster is a handy display resource when teaching your KS2 class about space.

As well as an informative poster (including information on the diameter of each planet, its distance from the sun and how long it takes to orbit the sun), there are smaller cut-out cards for children to use as a reminder, and even a blank version for them to colour and label themselves.
