The eccentricity measures how far off the centre each focus is, as a fraction of the distance from the centre to the extremity of the major axis.

How the orbits of the moon and the earth are different?
The orbit of the Moon is distinctly elliptical with an average eccentricity of 0.0549. The orbit of the Earth is distinctly elliptical with an average eccentricity of 0.01671123.
Which planets move in an elliptical orbit?
All the planets move with an elliptical orbit, but with a very low eccentricity.
Do planets orbit around the sun in a perfect circle?
All planets orbit the Sun in an elliptical orbit. An elliptical orbit is defined as having an eccentricity of between 0 and 1. (0 is a circular orbit). Anything over 1 is defined as a hyperbolic orbit.Mercury has the highest eccentricity of .205630 whereas the Earth has a near circular orbit with an eccentricity of 0.0167.Triton, a moon of Neptune has lowest eccentricity with a value as close to 0 as can be measured.
What is the motion of planets around the sun?
According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus.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.
Which planet's orbit is most nearly circular?
Although all planets have elliptical orbits, Venus has the least eccentric orbit (eccentricity of 0.00677323, where 0 would be circular)
How are the orbits of the earth and the moon different?
The orbit of the Moon is distinctly elliptical with an average eccentricity of 0.0549. The orbit of the Earth is distinctly elliptical with an average eccentricity of 0.01671123.

Is the orbit of Mercury highly elliptical or little elliptical?
The orbit of Mercury has the highest eccentricity of all the Solar System planets
Does the moon revolve around earth in a circular orbit?
No, the moon's orbit is elliptical with an eccentricity of about 0.55

What is Mercury's eccentricity?
All the planets have elliptical orbits, but Mercury and Mars have the greatest eccentricity. As to why Mercury's orbit is the most eccentric may be related to its proximity to the Sun.
What is the approximate compression of the earths orbit around the sun?
The Earth's orbit is almost circular. Technically, the "eccentricity" of the orbit is about 0.0167.
What type of ellipse does Pluto's orbit have?
The elliptical orbit of Pluto has a semi-major axis of about 39,5 AU (astronomic units), the eccentricity is about 0,249.
Does mars orbit the sun in a circle shape?
No. A circle is an unstable shape for an object orbiting another. An orbit is between slightly and very elliptical (egg-shaped). If an object is placed in a circular orbit, the orbit will quickly deteriorate to an elliptical orbit. Added: Mar's elliptical eccentricity is rather above average for a planetary orbit. Not quite as large as Mercury, but large enough.
Shape of earth and moons orbit?
All orbits are elliptical. Some, like Earth's are ALMOST circles, but every orbit has at least a little bit of eccentricity.
Is the orbit of moon around the earth is elliptical or round?
As seen by an observer on the Earth, the Moon's apparent orbit is distinctly elliptical. The orbit is subject to many perturbations and variations because of the Earth's elliptical motion around the Sun, and the fluid tidal envelope sloshing around the Earth. The eccentricity of the Moon's orbit varies between 0.026 and 0.077 .
