This informative poster features a diagram of the solar system. The path of each planet's orbit around the sun is indicated, and a mnemonic is given to help remember their order. Alongside the image of every planet, a 'fact card' gives its distance from the sun, diameter at equator, mass, time taken for one rotation, time taken to orbit the sun and number of moons. Three further diagrams indicate the effect of the sun in creating night and day, the moon's relationship to the earth and the alignment of sun, earth and moon needed for an eclipse. Col.ill.
