A _______________________ is a group of stars that forms a pattern.
The pattern is usually _________________ like an animal, a person, or an object.
Stars appear to ___________ across the sky at night.
This illusion is caused by the Earth’s ___________________ (spin) on its axis.
As Earth _________________ (orbits) around the Sun different constellations
become visible at different times of the year.

past used them to tell __________ and mark the ________________.
____________________ used to rely on them to know when to plant their crops.
Constellations that are visible all year round have been used to tell
________________.
_______________ used to rely on the stars to know which direction to travel at
night.
Planets
 A ______________ is a large body of rock or gas in space that moves around a
star.
 Planets DO NOT give off their own ______________.
