The orbital track of the earth around the sun is an ellipse.
Both the direction of rotation of the Earth around its axis and its orbital rotation around the sun are the same.
The orbital speed of the earth around its axis diminishes slowly.
The sun has an own movement through the universe opposite to the movement of the earth due to the gravitational forces of celestial bodies.
