One possible way would be to determine which orbit has the greater percentage difference between their maximum and minimum orbital velocities.
Two objects of the same mass will also move in elliptical orbits. Whether the two bodies are of the same mass or different, one focus of the elliptical orbit is the center of mass (barycenter).
The planet with the most elliptical orbit is Mercury. Second is Mars.
All orbits are conic sections. Repetitive orbits (e.g. earth's and other planet's orbits around the sun) are a type of conic section called an ellipse. One time pass orbits (e.g. some comets) are one of two other types of conic sections called either parabolic or hyperbolic.
Ellipse. One of Newton's Laws of Planetary Motion sate that the planets revolve in elliptical orbits with the Sun at one of the two foci.
subtract two from the period number
The elliptical orbit of planets is a result of the gravitation of the sun and the tangential velocity of the planet.
Two objects of the same mass will also move in elliptical orbits. Whether the two bodies are of the same mass or different, one focus of the elliptical orbit is the center of mass (barycenter).

The only orbitals that are very close to circular are those around a system with two stars. All other orbitals have an oval or elliptical shape
It is very improbable that any planet that orbits any star follows a circular path. Most, if not all, planets are in elliptical orbits around their respective stars, where the star is roughly at one of the two centers of the elliptical path. This means that the distance of any planet from its star is changing throughout the planet's year.
The planet with the most elliptical orbit is Mercury. Second is Mars.
Most orbits are elliptical; all NATURAL orbits are. There are two foci, or focuses, to an ellipse. The distance between the foci determines how eccentric, or non-circular, they are. If the two foci are in the same place, then the ellipse becomes a circle. So a circular orbit would have only one focus.
Technically an orbit is defined as a circular or elliptical path of one object around another object.So the Moon has one orbit.However, the Moon orbits around the Earth, and the Earth orbits around the Sun. The Sun orbits around the galactic core of the Milky Way. The Milky Way orbits around.... well we don't know, if it orbits anything.
No. In spherical elliptical geometry, for example, given the earth's North and South poles, there are an infinite number of lines of longitudes between them.
According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus. The shape of an ellipse is described by the eccentricity. For low eccentricity such as the planets' orbits have, the orbit is very close to being a circle but the most significant difference is that the Sun is off-centre.
