  11. 26. the curved path, usually elliptical, described by a planet

  3. 4. the movement or path of the earth or a heavenly body turning on its axis.
  4. 5. the periodic rise and fall of the waters of the ocean and its inlets, produced by the attraction of the moon and sun, and occurring about every 12 hours.

  12. 20. a loose collection of ice and dust
  13. 22. the complete or perfect shadow of an opaque body, as a planet
