Earth’s Yearly Orbit

Earth travels around the Sun on a long, almost circular path. It takes about one year to go all the way around once.

In the picture

  1. The Sun: the star at the center of the orbit.
  2. The orbit path: the loop Earth follows around the Sun.
  3. Earth: the planet moving along the loop.
  4. The motion arrow: the direction Earth travels along the loop.

Examples

  • A birthday comes around once each year.
  • After one full year, the same calendar month returns.
