  1. 3. A huge ball of gas that gives out heat and light energy.
  2. 8. Anything that orbits a planet or moon.
  3. 9. Orbit An orbit where a satellite passes over the North and South Poles. It will pass over all parts of the Earth during several orbits.
  4. 10. Radiation Another name for the heat energy that s transferred by radiation. IT can travel through transparent things and a vacuum (empty space).
  5. 12. Orbit An orbit where the satellite is over the equator and takes exactly 24 hours to circle the Earth, so it always stays over the same part of the Earth.
  6. 13. Spectrum The family of waves that includes lights, infrared, microwaves and radio waves.
  7. 16. A large objects that orbits a star. The Earth is a planet.
  8. 18. The unit of force.
  9. 20. All the galaxies and the space between them.
  10. 22. The force of attraction between anything.
  11. 23. Observatory Satellite A satellite used to take pictures of the Earth - for instance the to help forecast the weather.
  12. 24. A space probe that lands on a planet or moon.

  8. 14. Satellite A satellite made by humans
  9. 15. The amount of matters that that something is made of.
  10. 17. Satellite A satellite this not made by humans. The Moon is a natural satellite of the Earth.
  11. 19. The amount of force with which gravity pulls something towards the Earth. It is measured in newtons(N).
  12. 21. Probe An unmanned spacecraft that has cameras and other equipment to find out about other planets.
