What can you see? • You can see stars, the moon and some of the planets. • The planets you can see are Venus, Mars, Jupiter and Saturn. • You can also see groups of stars, which are called Constellations. Stars & Planets • At first glance, they all look the same, bright white dots. • Stars twinkle and planets don’t. • WHAT??? • If you look at a star it will blink at you, like a light being turned on and off very quickly. • A planet won’t blink. • Planets often appear earlier than stars and are lower in the sky. • They are also often brighter.
