In the summer, Ana looked up in the night sky and saw her favorite pattern of stars. Later in the year, Ana was observing the night sky and noticed she wasn’t able to see the same stars. What causes us to see only certain patterns of stars during certain times of the year?

• the Sun’s rotation

• the Earth’s rotation

• the Sun’s revolution

• the Earth’s revolution

When comets come close to the Sun they develop a tail that glows so we can see it from Earth. Asteroids do not develop tails like this. In what other way are asteroids different from comets?

• Asteroids are rocky while comets are made of ice and dust.

• Asteroids are smooth and round while comets are jagged and irregular

• Asteroids revolve around planets while comets revolve around the Sun.

• Asteroids form patterns in the sky while comets orbit the Sun between Mars and Jupiter.

The first astronauts walked on the Moon more than 50 years ago. Look at the picture of a footprint of an astronaut’s boot on the Moon.

• The pattern would be smaller because the stars moved closer together.

• The pattern of stars would appear to have moved together across the sky.

• The pattern would change because each star would have moved in a different direction.
