NGSS.HS-PS4-3

Use the image to identify the motion of the object relative to Earth.  Compare the absorption spectra of the star to what the star would look like if it were not moving at all relative to Earth.

• It is not moving

• It is moving away from Earth (Redshift)

• It is moving towards Earth (Blueshift)

• It is moving towards Earth (Redshift)
