The planets do NOT orbit in circles. They orbit the Sun in an ellipsoidal manner.
An ellipse has two foci. The Sun lies at one of the foci, the other might be deemed to be a 'blind' focus. The Sun does NOT lie at the centre of the ellipse.
Also the satellites(moons) orbit their parent planets in a similar manner.
It has also been discovered that the planets in an an ellipsoidal manner. That is as each orbit is completed the planet 'over-shoot' their starting point, and the ellipse does not close .
See Johannes Kepler, who gave us the Law of orbiting planets sweeping equal arcs in equal times , in 1602 AD.

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.
Which two planets overlap?
The two planets with overlapping orbits are Neptune and Pluto. These are the only two planets that have overlapping orbits.
Who discovered that planets have elliptical orbits?
Johannes Kepler proposed that these planets orbit the sun in ellipses, not circles. That is why we have Kepler's Law of Planetary Motion.
What are the four planets that have orbits from most to least?
All the planets have orbits so four cannot be picked out.
How Do Planets Travel Around The Sun?
the planets go around in circles around the sun
What is the difference between Copernicus and Kepler description of planetary orbits?
Kepler realised the planets orbits are not circles; they are ellipses.
Who worked out that the planets orbits are flattened circles?
Johannes Kepler, using measured planetary positional data provided by Tycho Brahe, showed that the orbits of the planets were ellipses ("flattened circles"), with the Sun at one focus of the eliipse.
Who correctly viewed the planets as orbiting the sun but incorrectly used circles to describe the orbits?
Copernicus

Do planets move in elliptical orbits?
The planets move intheir ellipticalorbits becauseof the gravitation of the Sun combined withthe inertial velocity of the planets(tangentialto their orbital paths). Mathematics shows the resulting orbits must be ellipses. (Some of the ellipses are in factalmost circles.)
Do moon orbits or circles the sun?
Moons orbit around its planet while the planets orbit the Sun, therefore moons circle the Sun.
Who discover that the planet have cliptical orbits?
Johannes Kepler discovered that the planets have elliptical orbits, and published the theory in 1618. It happened after he was given access to accurate measurements made by Tycho Brahe in Denmark. It took over 1000 years to discover, because the planets' orbits are very like circles, and a system using circles made a good model of a planet's orbit until observations became accurate enough to reach the proper answer.
What date did Johannes Kepler discover ellipses?
Kepler did not discover ellipses. In 1605 he discovered that the orbits of the planets were ellipses rather than perfect circles.
What is the main difference between the orbits of the inner and outer planets?
The planets revolve in elliptical orbits. The inner planets have orbits 230 million km or less from the Sun. The outer planets have orbits 775 million km or greater.
What are the planets orbits?
The planets orbits are the routes or paths that the planets follow around our sun. One orbit is one trip around the sun (one year).
Who said the planets traveled in oval orbits?
Everyone from the ancient Greeks on knew that the planets move in oval-type orbits, which were simulated by systems of circles. Later, after years of hard work, Johannes Kepler published the laws of planetary motion in 1618 which showed that the orbits are more accurately represented by ellipses, and each planet has its own ellipse with the Sun at one focus. Ellipses make very good approximations to the actual orbits of planets, but the gravitational effects of the other planets, especially Jupiter, mean that the planets depart slightly from true elliptical orbits. That is taken care of by regular updates to the orbital elements of the planets, which are numbers which describe the sizes and shapes, orientation and inclination of all the planets' elliptical orbits.
Which two planets overlap?
The two planets with overlapping orbits are Neptune and Pluto. These are the only two planets that have overlapping orbits.
