What shape are the planets orbits?
Planetary orbits are usually taught to be circular. However, they are truly more elliptical (oval shaped).
Does the orbit is very elliptical?
No the planet's orbits are not VERY elliptical but yes, they are somewhat elliptical. They are not just rotating in a circle. More like an oval.
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.
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).
Bohr suggested that electrons circle the nucleus in what type of orbit?
False -- it's more elliptical

Does the elliptical cross section created when a plane cuts through a cone help prove that orbits of the Earth and other planets are elliptical in nature?
It would be more accurate to say that the mathematical study of the nature of an ellipse, showing that it can result from cutting through a cone in a particular way, helps to understand the nature of elliptical planetary orbits, but it does not prove that planets have elliptical orbits. It requires actual astronomical observation of planetary orbits to determine what kind of orbits they are.
Are elliptical orbits circular?
An ellipse is a closed curve that is not circular (the curve is not a constant distance from any point inside of the curve). While some planetary orbits are relatively circular, others are more elliptical, that is having an oval shape with a varying distance from the Sun.
Among elliptical orbits are some more circular than others?
Yes some elliptical orbits are more circular than others
What is the shape of all the orbits of comets?
Comets travel in highly elliptical orbits. See link for more.
Does the orbit is very elliptical?
No the planet's orbits are not VERY elliptical but yes, they are somewhat elliptical. They are not just rotating in a circle. More like an oval.
Are some elliptical orbits more circular than others?
Yes, true.
What is the shape of the orbit a comet has?
The orbits of periodic comets and the orbits of planets have the same geometric shape.Every closed gravitational orbit is an ellipse. But the eccentricity of the cometary ellipsesare almost all greater than the eccentricities of the planetary ones.

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.
