Name:______________ Sky Science Review Questions 1. Are stars made mostly of solids, liquids, or gases? __________________ 2. What is the name of the galaxy in which our Solar System is located? ___________________ 3. Which star is closest to the Earth? _______________________ 4. List the things that EMIT light: ________________________________________ 5. List the things that REFELCT light: ____________________________________________ 6. How many planets are in our Solar System?_________________ 7. Which planet is nearest the Sun?_______________________ 8. Which planet is farthest from the Sun?_______________________ 9. Which planet has the biggest, most easily-seen rings orbiting it? _____________________ 10. Are the inner planets made of rock or gas? _______________________ 11. What are the icy objects with huge tails that orbit the Sun? ______________________ 12. Which planet is called the "red planet"? ______________________ 13. Is the Sun a star, a planet, or a comet?_______________________ 14. Where is the Sun hottest?_______________________ 15. Do we always see the same side of the moon from Earth? ________________ 16.Does the moon have an atmosphere?_______________________ 17. During a lunar eclipse, the shadow of what celestial body blocks our view of the moon? _____________ 18. Why is it dangerous to look directly at the sun? How could you protect your eyes but still view the sun? __________________________________________________________________________ __________________________________________________________________________ Name:______________ 19. What are three major differences between the inner and outer planets? __________________________________________________________________________ __________________________________________________________________________ 20. Use the diagram to answer the questions. Label each of the moon phases. Shade in the phase so it shows what we would see on earth. A____________________ B______________________ C__________________ D____________________ E______________________ F__________________ G____________________ H______________________ 21. The moons pattern takes approximately 28 days to complete. If the moon was in a full moon phase on January 12th, what would the moon look like on January 20 th? Moon Phase on January 12th ________________________________ Moon Phase on January 20th ________________________________ Name:______________ 22. Draw what the moon phase will look like when the moon is directly between the earth and sun. 23. Which direction does it look like the constellations are always rotating? Why does this happen? __________________________________________________________________________ __________________________________________________________________________ Use the words in the word bank to answer the questions. Word Bank: asteroid gaseous Mercury rock Sun ecliptic moons nine Jupiter Mars Earth center inner Solar System Pluto Our ___________________________________ consists of the sun, ____________________________ planets (and their moons), an ____________________________ belt, and many comets and meteors. The Sun is the ____________________________ of our Solar System. The planets, their moons, the asteroids, comets, meteoroids and other rocks and gas all orbit the ____________________________. The nine planets that orbit the sun are (in order from the Sun): ____________________________, Venus, Earth, Mars, ____________________________ (the biggest planet in our Solar System), Saturn (with large, orbiting rings), Uranus, Neptune, and Pluto. A belt of asteroids Name:______________ (many minor planets made of rock and metal) orbits between ____________________________ and Jupiter. These objects all orbit the Sun in roughly circular orbits that lie in the same plane, called the ____________________________ (____________________________ is an exception to this; it has an elliptical orbit that is tilted over 17° from the ecliptic). The ____________________________ planets (those planets that orbit close to the Sun) are quite different from the outer planets (those planets that orbit far from the Sun). The inner planets are Mercury, Venus, ____________________________, and Mars. They are relatively small, composed mostly of ____________________________, and have few or no moons. The outer planets are Jupiter, Saturn, Uranus, Neptune, and Pluto. They are mostly huge, mostly ____________________________, ringed, and have many ____________________________ (again, the exception is Pluto which is small, rocky, and has one moon).
