What is the shape of the orbit of all planets in our solar system responses and relationship between the distance from the Sun and the average orbital velocity?
Today, we've mapped out the orbits of the planets to incredible precision, and what we find is that they go around the Sun all of them in the same two-dimensional plane, to within an accuracy of, at most, 7° difference.The orbit of every planet is an ellipse with the Sun at one of the two foci. A line joining a planet and the Sun sweeps out equal areas during equal intervals of time. The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. Earth's orbit is not a perfect circle. It is elliptical, or slightly oval-shaped. This means there is one point in the orbit where Earth is closest to the Sun, and another where Earth is farthest from the Sun.All planets move in elliptical orbits, with the sun at one focus. This is one of Kepler's laws. The elliptical shape of the orbit is a result of the inverse square force of gravity. The eccentricity of the ellipse is greatly exaggerated here.The Sun and all eight planets of the solar system are round why? The gravitational force of a planet's mass pulls all of its material toward the center, smoothing out any jarring non-roundness. Many of the smaller bodies of the solar system are not rounding because their gravity is not enough to smooth out their shape. The orbit of earth around sun and orbit of all other planets are not circular but in stretched circles like oval. These shapes are called ellipses. The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus. The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus. If Earth were a perfect sphere, calculations of depth and distances would be easy because we know the equations for those calculations on a sphere. However, the Earth more closely approximates an ellipsoid, which is what a ball looks like if you sit on it.The orbital period is directly related to the average distance between the planet and the Sun. This law implies that planetary orbital velocity decreases with increasing distance from the Sun. The further away from the Sun it is, the slower the planet's orbital speed and the longer its path. Both of those factors result in taking longer to make one complete orbit and a planet having a longer year.
It is physically impossible for a free macro body to revolve around another moving body in any type of geometrically closed path. This can be observed by watching a person trying to move around another person running along a defined path. Planets are free macro bodies, the central body (sun) is a moving body and the circular/elliptical path is a geometrically closed path.
In order to achieve a geometrically closed planetary orbit, the central body has to stay in space without translation. I am very much interested to know how the sun maintains its stationary location in space.
Yes, the orbital period is directly related to the average distance between the planet and the Sun. This law implies that planetary orbital velocity decreases with increasing distance from the Sun. Here's an easy way to think about it: the more distant a planet is from the sun, the greater its orbital period. The further away from the Sun it is the slower the planet's orbital speed and the longer its path. Both of those factors result in taking longer to make one complete orbit and a planet having a longer year. The orbits of most of the planets have a small eccentricity and are nearly circular so their distance from the sun doesn't very much. The orbits of comets have a high eccentricity so their distance from the sun varies significantly over the orbit. When a planet is closer to the Sun the Sun's gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun's gravitational pull is weaker, so the planet moves slower in its orbit.The further away from the Sun it is the slower the planet's orbital speed and the longer its path.

Do you really believe in geometrically closed planetary orbits around their central bodies?
The orbits of most of the planets have a small eccentricity and are nearly circular so their distance from the sun doesn't vary much.

The orbits of comets have a high eccentricity so their distance from the sun varies significantly over the orbit. But Earth's distance from the sun doesn't change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun's light and warmth most directly. The closer the planet is to the Sun, the greater the pull of the Sun's gravity, and the faster the planet orbits. The orbit of every planet is an ellipse with the Sun at one of the two foci.

These shapes are called ellipses. Earth is an oblate spheroid. This means it is spherical in shape, but not perfectly round. It is slightly bulged at the equator and is flattened at the poles.The Earth is spherical but, flat at the poles and bulges at the Equator. The shape of Earth is very unique. It is called a Geoid (earth shaped). The Earth moves around the Sun (Revolution).
