Venus has an eccentricity of 0.00677323 Neptune has an eccentricity of 0.00858587 Triton, a moon of Neptune, orbit is as close to a perfect circle with an eccentricity of 0.000016 The Earth for comparison has an eccentricity of 0.01671022
The Earths orbit is fairly un-eccentric when compared to the other planets, with only Neptune and Venus having more regular (less eccentric) orbits. The eccentricity of earths orbit is 0.0167, the closest to this is Neptune's, with a value of 0.00859
Oh, what a delightful question! Neptune is known for its interesting orbit around the Sun, with an eccentricity of about 0.0097. This means that Neptune's orbit is slightly elongated, giving it a bit of a different path compared to other planets in our solar system. How wonderful it is to learn about the unique characteristics of each planet!

Mercury has an orbital eccentricity most similar to the moon's orbital eccentricity, which is about 0.2056. Mercury's eccentricity is approximately 0.206.

Jupiter, Saturn, Uranus and Neptune. Because of the eccentricity of Plutos orbit it is sometime inside the orbit of Neptune.
There is no strict pattern. Mercury, the innermost planet, has the highest eccentricity. Venus, the next nearest to the sun, and Neptune, the outermost have the least eccentricities.

None of the planets orbit the sun perfectly in a circle, there is a degree of deviation from this perfect circle called eccentricity. The higher the eccentricity (more more the eccentric the orbit is) the further away from this perfect circle the orbit is. The planet that deviates most from a perfect circle, having the highest eccentricity, is Neptune. Neptune also has the highest axial tilt, tilted over onto its side as it orbits the sun.
Earth has an average eccentricity in its orbit of 0.0167. This compares with 0.0068 for Venus and 0.205 for Mercury, which are the minimum and maximum eccentricities in the eight planets. So, the Earth's orbit is not too far from circular. In order of increasing eccentricity, the list of planets is: Venus Neptune Earth Uranus Jupiter Saturn Mars Mercury.
Planets don't have circular orbits; all orbits are ellipses. A circle has one center, but an ellipse has two focuses, or "foci". The further apart the foci, the greater the eccentricity, which is a measure of how far off circular the ellipse is. Venus has the lowest eccentricity, at 0.007. Neptune is next with an eccentricity of 0.011. (Earth's orbit has an eccentricity of 0.017.) So, Venus has the shortest focus-to-focus distance.
Mercury has an orbital eccentricity most similar to the moon's orbital eccentricity, which is about 0.2056. Mercury's eccentricity is approximately 0.206.
Many asteroids have an eccentric orbit, that is, the orbit's ellipse is very stretched. Pluto is just one of many planetoids with this characteristic.
Venus has the orbit closest to a circular orbit. Neptune's is not too bad also. Look for low' eccentricity' rating, the closer to zero the more circular.
