The eccentricity value measures how non-circular an orbit is. The planets in decreasing order of eccentricity with their approximate eccentricity values are:
# Pluto: 0.25 # Mercury: 0.21 # Mars: 0.093 # Saturn: 0.056 # Jupiter: 0.048 # Uranus: 0.047
# Earth: 0.017 # Neptune: 0.0086 # Venus: 0.0068

Which planet has the perfect circular orbit?
No planet has a perfectly circular orbit, though Venus has the least orbital eccentricity of any planet in our solar system.
What is the shape of the path of a planet around the sun called?
An eliptical orbit. In theory a planet could also have a circular orbit, but no planet that we know of has a perfectly circular orbit, although some have a nearly circular orbit.
Will the greatest difference in seasons occur on a planet that has a circular orbit?
The greatest difference in seasons will occur on a planet that has a circular orbit. This is because winds are created this way.
What planet orbit around the sun is most nearly circular?
Mercury
A planet or moon does when they move in a circular pathway around something else?
An orbit.

Which planet has least perfectly circular orbit?
Mercury.

Which planet has an elongates orbit?
All planets have at least some elongation or orbital eccentricity and thus not a perfectly circular orbit. Since Pluto was demoted from true planet status, Mercury is now the planet with highest eccentricity (of about 0.21)
Which 2 planets do not have a circular orbit?
No planet's orbit is perfectly circular. They are all elipses.
What the meaning of the ORBIT?
an orbit is the circular movement of a planet going round the sun, or a moon going round a planet. Gravitaional force is what creates the orbit.
Why does the Earth have an elliptical orbit around the sun?
I'll assume you mean: "... as opposed to a circular orbit". That is caused by the fact that for a circular orbit, a planet needs a VERY PRECISE SPEED. Change the speed slightly (at a particular point in the orbit), and the orbit immediately becomes elliptical.
What is a closed orbit?
With an open orbit, the object never returns. Examples would be a satellite in an unstable (open) orbit crashing down on Earth or a passing comet on a hyperbolic orbit which will leave our solar system (ejection loss). Closed orbits are the stable, planet-like orbits where objects return in a predictable manner.
A planet or moon does when they move in a circular pathway around something else?
An orbit.
What planet orbit around the sun is most nearly circular?
Mercury
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.
