A satellite in low orbit typically about 800 km from the Earth is exposed to an immense gravitational pull and has to move at considerable speed in order to generate a corresponding centrifugal force. There is a direct connection between the distance from the Earth and the orbital velocity of the satellite. At a distance of 36,000 km, the orbiting time is 24 hours, corresponding to the Earth's rotation time. At this distance, a satellite above the Equator will be stationary in relation to the Earth.
Therefore, the distance between the earth and the sun varies throughout the year. At its nearest point on the ellipse that is the earth's orbit around the sun, the earth is 91,445,000 miles (147,166,462 km) from the sun. This point in the earth's orbit is known as perihelion and it occurs around January 3.The earth is farthest away from the sun around July 4 when it is 94,555,000 miles (152,171,522 km) from the sun. This point in the earth's orbit is called aphelion.herefore, the distance between the earth and the sun varies throughout the year.
