What is the relationship between earths distance form the sun and earths orbital velocity?
Earth’s orbit around the sun forms an ellipse, not a circle. This means that at times Earth will be farther from the sun than at other times. When we’re farthest from the sun our velocity around it will be slower than when our orbit takes us closer to the sun. For example, today we’re 92,027,559.06 miles from the sun and moving at 30.07 km/second. Next June we’ll be farther from the sun (..94,816,272.97 miles…) from the sun and moving at 29.34 km/second. Those solar system planets that are farther away from the sun than Earth move slower in their orbits. For example, Neptune is farther away from the sun than Earth and it moves at about 5.44 km/second. Mercury is the planet closest to the sun and is moving at 39.68 km/second.
