Planets follow elliptical orbits, it would be extremely unlikely for any natural orbit to be perfectly circular. Though the orbits of some of our solar system's planets, shrunk down to fit on a standard book page, would appear to be nearly circular.

∙ 13y agoCannot be answered with a "yes" or "no", because there is so much variance. In our own solar system, Venus has an orbit that, while elliptical, is quite close to being a perfect circle. Dwarf planet Pluto has an orbit that looks like a very compressed ellipse - not at all circular. The others fall somewhere in between.

∙ 10y agoNo, all orbits are ellipses. Some of them are pretty close to being circles; for example, the Earth's orbit has an eccentricity (the difference between the semi-major and semi-minor axes) of only 3%, so it's darn close. But still an ellipse.

Who thought that the earth was the centre of the universe and that the planets had circular orbits?
Ptolemy, but he was wrong the sun is in the center and planets have elliptical orbits.
Why your planets revolve in elliptical orbit rather than circular orbit?
Circular orbits are unstable; any outside influence (i.e. other planets) will distort them. Elliptical orbits are self adjusting.
Who proposed the circular orbits of the planets around the sun in the 1500s?
Nicolas Copernicus.
Are the orbit of planets circular and How may their path be best described?
The orbits of planets are not quite circular. They are slightly elliptical. An ellipse is like a circle which has been squished.
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.
If the planets' orbits were circular would their distance from the sun always be the same?
Yes. However, the orbits of all planets are elliptical. Some planets, like Earth, have a very low "eccentricity", which is a measure of how non-circular they are. Earth's orbit is not quite circular, but fairly close. Other planets, like Mars, have more eccentric orbits, and their perihelion and aphelion distances are substantially different.
Does circular motion occurs only occures only on earth?
No, there are circular movements just about anywhere: planets, moons and stars rotating, planets orbiting their stars, moons orbiting their planets, and stars orbiting their galaxies, often in orbits that are fairly circular, etc.
Who thought that the earth was the centre of the universe and that the planets had circular orbits?
Ptolemy, but he was wrong the sun is in the center and planets have elliptical orbits.

What two planets has the most circular orbits?
Pluto and Abby University
What evidence do you have that the planets move in elliptical orbits around the sun and not in circular orbits?
Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.
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.
Who proposed the circular orbits of the planets around the sun in the 1500s?
Nicolas Copernicus.

The orbits of planets are not quite circular. They are slightly elliptical. An ellipse is like a circle which has been squished.
Does Earth cross Neptune's orbit?
No, all eight of the planets have orbits that are fairly close to circular, so none of their orbits intersect. However, Dwarf Planet Pluto has an orbit that is so elliptical that sometimes it is closer to the sun than Neptune.
