When we look at the night sky. It seems that the planets are always changing their positions while the stars appear to be fixed. ………… . One star, for example, though it actually moves quite fast, would take over two hundred years to move a distance equal to the diameter of the Earth's moon. It is only when we compare the records ancient peoples kept of the skies with the present day that we can see the stars really do move.

Planets also seem to have a steady light, while stars twinkle

In fact, stars are always moving, but they are so far away that we cannot see any change in their position

Astronomers can only estimate the total number of stars in the universe

Distance cannot be learned from a star's magnitude alone, because its magnitude depends upon its size and brightness as well

Talking about star signs is often a good way to begin a conversation with a stranger
