  1. 3. - unequal forces on an object that may result in a change in position, direction, or motion.
  2. 4. - the spinning of an object on an axis
  3. 6. - ring of icy objects out past our planets
  4. 7. - the force that causes objects with mass to attract one another.
  5. 9. - next planet to hopefully land a human on
  6. 11. - planet covered in an acidic atmosphere
  7. 15. - missions to land humans on the moon
  8. 17. - the revolving of one object around another in an oval-shaped path called an ellipse. The planets in the solar system orbit the sun in elliptical orbits.
  9. 19. - this planet has over 85 moons
  10. 20. - a push or a pull that can result in a change in the motion of an object.
  11. 23. - the way in which a whole or mixture is made up.
  12. 24. - Third largest planet in our solar system
  13. 25. - a small object that enter Earth’s atmosphere from space and burns due to friction, causing light to be released.
  14. 26. - large and small rocks or metallic masses orbiting the sun; made up of materials similar to those that formed the planets.

  1. 1. - a characteristic of matter that you can observe and measure without changing the identity of the matter.
  2. 2. - last planet in our solar system
  3. 5. - the gravitationally curved path of an object around a point in space.
  4. 7. - the force that pulls two objects towards each other. The greater the mass of an object, the greater its attraction force; the further apart the objects are from one another, the weaker the attraction force.
  5. 8. - First artificial satellite
  6. 10. The first planet from the sun
  7. 12. - the Sun together with the group of planets and other celestial objects that are held by its (the Sun’s) gravitational attraction and revolve around it.
  8. 13. - Io and Titan for example
  9. 14. - the way in which a whole or mixture is made up.
  10. 16. - a celestial body of ice, dust, and rock with an elongated and elliptical orbit.
  11. 18. - the movement of an object in an elliptical path around a center.
  12. 21. - only planet with liquid water
  13. 22. - Has Rings
  14. 27. - An engine that provides thrust directly through the burning of its fuel without requiring the intake of air.
