Why do planets have circular and elliptical motions in the solar system?

The scientific explanation lies in Kepler's laws of planetary motions, which were discovered by Newton to be linked with the law of gravity. All the planets have elliptical orbits, and many of those are close being circular.

Does all planets have elliptical orbits?
Yes, none of the planets in our solar system have exactly circular orbits, though some are more eccentric than others.
Which planets' motions were described with epicycles in the Ptolemaic system?
All the known planets
What is the shape of the orbits of the planets around the sun?
The planetary orbits of our solar system are considered "elliptical." This includes "circular" orbits, as a circle is a type of ellipse. In astrodynamics, an elliptical orbit and a circular orbit both fit into the description of a Kepler Orbit.
Do The planets maintain circular orbits around the Sun?
The orbit of the planets in our Solar system are not perfectly circular, but eliptical. Each planet also has its own unique orbit, no two planets share an identical orbit. Because of the elliptical (oval) orbit of planets some get close to each other or cross the path of another planet's orbit.
How is the orbit of the earth around the sun shaped?
All planets in our solar system, including the the Earth have an elliptical orbit around our Sun. In Earth's case, the orbit is nearly circular.
What is the orital shape of the planets in our solar system?
All of the planets in our solar system have an elliptical orbit around the sun.
Which planets orbital shape is similar to Jupiter?
All planets in our solar system have elliptical orbits.
What evidence do you have that planets move around the sun in an elliptical orbit?
That theory is supported by observation, and is predicted by other theory that isconfirmed by both observation and experiment.1). A system of planets moving around the sun in elliptical orbits is the simplest structurethat produces the motions of the planets that we actually see in the sky.(demonstrated by Kepler, working with Tycho's observational data)2). A theory of universal gravitation, proportional to the product of masses and inverselyto the square of the distance between masses, predictsthat planets will move aroundthe sun in elliptical orbits.(Newton)
What changes Kepler had to made in order to fit the observations of Tycho Brahe into the heliocentric system of Copernicus?
He wrote that other planets for example, Mars moved in elliptical, or oval, orbits instead of circular ones.
Is the orbit of Mercury highly elliptical or little elliptical?
The orbit of Mercury has the highest eccentricity of all the Solar System planets
How did Johannes Kepler figure out that the planets had an elliptical orbit?
The circular orbits that were being used at the time to model the solar system did not quite work with mathematical predictions or observations. Kepler found that elliptical orbits provided more accurate predictions of where the heavenly bodies would appear in the sky.
What is the same for all planets in the solar system?
They all have elliptical paths around the Sun.
