  1. 5. An icy chunk of frozen gases, water, and dust that continually orbits the sun
  2. 12. A complete orbit of a planet around the sun or of a moon around a planet
  3. 14. An eclipse in which the moon passes between the sun and the earth
  4. 16. our closest star
  5. 18. A complete spin of a planet or moon on its axis
  6. 20. tens to hundreds of times larger and hundreds of times more luminous than the sun
  7. 21. A cloud of interstellar gases and debris
  8. 22. An unmanned research spacecraft sent beyond Earth’s orbit
  9. 25. A rocky object in space that is smaller than an asteroid
  10. 26. Stars that regularly or repeatedly change in magnitude
  11. 29. small- and medium-sized stars
  12. 31. hundreds of times larger than the sun and thousands of times brighter
  13. 33. A telescope that uses only lenses to make objects appear larger
  14. 35. A bright cloud of gas on the sun’s surface; usually accompanies sunspots
  15. 36. A group of stars that appear to form a picture or pattern in the sky
  16. 38. the distance that light travels in one year
  17. 39. A meteor that does not burn up in Earth’s atmosphere and hits Earth’s surface
  18. 40. stars go through periods of swelling and brightening, then shrinking and dimming
Down
  1. 1. brightness of a star
  2. 2. An object that orbits the sun and that has enough gravity to be spherical but not enough gravity to have an orbit clear of other objects of simi
  3. 3. A meteoroid that lights up because of friction as it moves through Earth’s atmosphere
  4. 4. Irregularly shaped pieces of rock, metal, and dust that orbit the sun
  5. 6. does not change its absolute magnitude but does change its apparent magnitude
  6. 7. Any object that orbits another object in space
  7. 8. he death explosion of a massive star
  8. 9. a true brightness of a star
  9. 10. An area of extreme gravitational force that may result from the collapse of a massive supergiant star
  10. 11. A small star group of three or four stars
  11. 13. An eclipse caused when the earth blocks part or all of the sunlight that is usually reflected by the moon; occurs when the moon passes through Earth’s shadow
  12. 15. he death explosion of a massive star
  13. 17. The event that occurs when a celestial body completely eclipses another celestial body
  14. 19. A star group containing two stars that revolve around each other
  15. 23. A telescope that uses lenses and mirrors to make objects appear larger
  16. 24. A device that breaks down light into all its colors; similar to a prism
  17. 27. The scientific study of the stars and heavenly objects
  18. 28. A term describing the rocky, dense, and Earthlike planets that are closest to the sun
  19. 30. what the brightness of the star appears to the human eye
  20. 32. Energy emitted in colors of light near Earth’s poles, caused by solar wind and Earth’s magnetic field
  21. 34. Any of the outer planets, Jupiter, Saturn, Uranus, and Neptune, which are made mostly of gases
  22. 37. A large object that orbits the sun and that has enough gravity to be spherical and to have an orbit clear of other objects of similar size other than its moons
  23. 41. A star that suddenly flares and becomes hundreds or thousands of times brighter than normal
