Astronomy review

  1. 1. Astronomy Review By Beverley Sutton Pueblo Gardens PreK-8
  2. 2. Astronomical Unit• The distance from Earth to the Sun is one Astronomical Unit.• The A.U. helps make the vast distances in our Solar System more manageable• Anything closer than Earth is a fraction of an A.U.• Anything further away is a multiple of an A.U.
  3. 3. Using the A.U. in our Solar System
  4. 4. Light Year• the distance that light travels in one year• One light year is about 10 trillion kilometers!• Light from the sun takes only 8 minutes to reach Earth … i.e. light travels 150 million km in 8 minutes)
  5. 5. Scale• the ratio of a displayed drawing, model, or map to the actual physical size or distance• A good example would be a scale on a map or the Play-Doh™ planets we made
  6. 6. Scale model of the Solar System
  7. 7. Solar System• the sun, and all the planets, dwarf planets, moons, comets and asteroids that orbit the sun
  8. 8. Planet• Any of the eight large heavenly bodies revolving about the sun and shining by reflected light• Also, any similar body revolving about a star other than the sun
  9. 9. Our Planetsin the order of their proximity to the sun • My – Mercury • Very – Venus • Elegant – Earth • Mother – Mars • Just – Jupiter • Served – Saturn • Us – Uranus • Nachos – Neptune
  10. 10. Star• a large, spherical celestial body consisting of a mass of gas that is hot enough to sustain nuclear fusion and thus produce radiant energy
  11. 11. Our Sun is a Star
  12. 12. Gravity• the attractive force between two objects; its magnitude depends on their masses and the distance between them.
  13. 13. Ellipse• An elongated circle, or oval shape; the shape of the planets’ orbits
  14. 14. Orbit• the path of an object as it revolves around another object in space
  15. 15. Revolve [around]• the movement of an object around another object
  16. 16. Axis• an imaginary line that passes through Earth’s center and the North and South poles, about which Earth rotates.
  17. 17. Season• one of four natural divisions of the year—spring, summer, autumn (fall), and winter.• Caused by the tilt of Earth’s axis which changes the angle of the Sun’s rays as Earth orbits the Sun.
  18. 18. Reason for the Seasons
  19. 19. Equinox & Solstice
  20. 20. Compass• a device used to determine geographical direction, usually consisting of a magnetic needle mounted on a pivot, aligning itself naturally with the Earths magnetic field so that it points to the Earths geomagnetic north or south pole
  21. 21. Rotate [on]• the spinning motion of a planet about its axis
  22. 22. Moon Phase• any of the forms, recurring in cycles, in which the Moon appears in the sky; the percentage of illumination on the visible face of the moon.
  23. 23. Eclipse• the partial or total blocking of the light of one object by another, casting a shadow on the other object Solar Eclipse
  24. 24. Tides• the rise and fall of the level of water in the ocean
  25. 25. Constellation• a pattern of stars in the sky
  26. 26. Cluster• a loose, irregular grouping of stars
  27. 27. Galaxy• a giant structure that contains billions of stars
  28. 28. Universe• all of space and everything in it
