The earth's orbit around the sun is elliptical, so the earth moves at a constantly varying velocity as it moves closer to the sun (perihelion) or further away (aphelion). The earth's angular velocity (speed of movement) is considerably greater at perihelion than it is at aphelion.he earth gets through 10% of its path in the same length of time whether it is at aphelion (moving slowly) or perihelion (moving fast). The absolute speed at which the earth moves varies, but the rate at which it orbits is constant.
In the Solar System, orbital inclination is usually stated with respect to Earth's orbit. In the Solar System, the inclination of the orbit of a planet is defined as the angle between the plane of the orbit of the planet and the ecliptic. Therefore, Earth's inclination is, by definition, zero.
