0.016710220 is the Earth's orbital eccentricity
The eccentricity of Psyche's orbit is 0.140
0.20563069
Of the planets in our solar system, Venus has the smallest 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.
0.016710220 is the Earth's orbital eccentricity
The eccentricity of Psyche's orbit is 0.140
It would have an eccentricity of 0.
Pluto's orbit DOES NOT overlap the orbit of the asteroid Ceres. But it does overlap the orbit of the planet neptune
The eccentricity of the Earth's orbit is currently about 0.0167; that rounds to zero.

Of the planets in our solar system, Venus has the smallest eccentricity.
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 you are referring to is the eccentricity of the planet's orbit around the sun. Eccentricity of a circular orbit is 0.0, whereas the eccentricity of an extremely elongated orbit is 1.0. So the closer the eccentricity of a planet's orbit is to 1.0, the more elongated is its orbit around the sun. Many extra solar planets have high eccentricities in accordance with their parent stars. In our solar system Mercury ( .20563) and Pluto (.24880766) have the highest eccentric orbits.
The orbit has an eccentricity of 9.3%
