How Do Objects in the Sky Appear to Move?

• Stars, planets, and other objects move in space, but their actual motions and their apparent, or visible, motions may be very different.

• The apparent motion of objects in the sky depends on the motions of Earth.

Multiple Choice

The apparent motion of objects in the sky depends on what?

• The movement of Earth

• The movement of the galaxy

• The movement of the planets

• The movement of the sun

How Do Objects in the Sky Appear to Move?

• Stars generally appear to move from east to west through the night.

• This apparent motion is caused by Earth’s turning from west to east.

• The sun’s apparent motion during the day is also caused by Earth’s motion.

Multiple Choice

It seems the stars move from what direction to what direction?

• East to west

• West to east

• North to south

• South to north

How Do Objects in the Sky Appear to Move?

• Which constellations you can see varies from season to season.

• These seasonal changes are caused by Earth’s orbit around the sun.

• Each night, the position of most stars shifts slightly to the west.

Multiple Choice

Why do you see different constellations based on the season?

• It’s based on Earth’s orbit around the sun

• It’s based on the moon’s orbit around the Earth

• It based on the sun’s orbit around the Earth

How Do Objects in the Sky Appear to Move?

• Because the planets all orbit the sun in about the same plane, they appear to move through a narrow band in the sky.

• This band is called the zodiac.

Multiple Choice

What is the narrow band the planets seem to move through in the sky called?

• Zodiac

• Constellations

• Planets
