Like all planets in our solar system, the Earth is in an elliptical orbit around our Sun. In Earth's case, its orbit is nearly circular, so that the difference between Earth's farthest point from the Sun and its closest point is very small. Earth's orbit defines a two-dimensional plane which we call the ecliptic.The Earth with its Sun.he Earth's orbit is in the shape of an ellipse, so that sometimes the Earth is a little bit closer to the Sun than at other times.
The Earth rotates (spins) counter-clockwise as viewed from above the North Pole, which is also from above the ecliptic plane of the solar system. This is the arbitrary up and down convention that allows us to say which direction the Earth is spinning. Most other objects in the solar system spin and orbit counter-clockwise as well. Depending on your location on the planet, the Earth's spin (west to east) could be seen as clockwise or counter-clockwise. In the Northern Hemisphere, looking south toward the equator, the Earth turns counter-clockwise.
