1 FINAL REVIEW: ASTRONOMY 1. Which body in our solar system is classified as a star?(1) Earth (2) Mars (3) Venus (4) Sun2. The diagram below shows Earth, as viewed from space,as it moves around the Sun.*Base your answers to questions 5-7 the diagrambelow which shows the position of Earth and four positions of the Moon during one orbit of Earth.X5. On the diagram, draw an X to show where theSun would need to be located to create the Moon phases shown.6. Which letter in the diagram shows the positionof the Moon when an observer on Earth sees a fullMoon?7. What motion is represented by the arrows inthe diagram? _________________________Approximately how long does it take Earth to move fromposition A to position B?(1) 1 year (2) 6 months (3) 1 day (4) 12 hours3. The Sun appears to move across the sky during theday. The best explanation for this apparent motion isthat Earth is:(1) rotating on its axis. (2) revolving around the Sun.(3) much smaller than the Sun. (4) tilted on its axis.POSITION CREVOLUTION
