Across
  1. 6. The gradual rotation of Earth's entire elliptical orbit around the Sun, occurring on a roughly 112,000-year cycle.
  2. 9. elliptical, orbital path earth takes around the sun.
  3. 10. A slight "nodding" or irregularity in the precession of the axis, caused primarily by the gravitational pull of the Moon.
Down
  1. 1. a slow 26,000 year of earth rotational axis much like a spinning top
  2. 2. the spinning of the earth on its own imaginary axis.
  3. 3. end
  4. 4. Orbit: The Solar System orbits the center of the Milky Way Galaxy. It takes Earth and the Sun about 230 to 250 million years to complete one full orbit around the galactic center.

  6. 7. System Motion The entire solar system—including Earth—is moving toward the constellation Hercules (specifically the star Vega) at approximately \(12 \text{ miles/s}\) (about \(43,200 \text{ mph}\)) relative to neighboring stars.
