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 simplest and most convincing proof that the Earth's is round is to examine a photo of our planet taken from space or to orbit it in the space shuttle. There can be no doubt from such evidence that the Earth is round, or more correctly, a sphere.. The word round refers to a circular shape, like the shape of a quarter when held flat in your hand. The proper term to describe the Earth's shape is spherical. A sphere appears round when viewed from any direction in space. It's okay to use the term round to refer to the shape of the Earth, so long as you're aware of this distinction.
