eccentricity = distance between foci

length of major axis
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.
The Earth's orbit is almost circular. Technically, the "eccentricity" of the orbit is about 0.0167.
The relationship between distance from the Sun and the period of rotation is described by Kepler's Third Law, which states that the square of a planet's orbital period is proportional to the cube of its average distance from the Sun. As for eccentricity, there isn't a direct relationship with distance; eccentricity measures the shape of an orbit, which can vary among planets at similar distances from the Sun. However, generally, planets further from the Sun tend to have more circular orbits, resulting in lower eccentricities.
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.

Eccentricity is the measure of how much the conic section diverges into its circle form. One of the formulas for eccentricity is e=c/a this formula can be used to get the eccentricity of the ellipse.
(sa-sp)/(sa+sp)
To determine the eccentricity of a conic section, we typically use the formula ( e = \frac{c}{a} ), where ( c ) is the distance from the center to the focus and ( a ) is the distance from the center to a vertex. If ( c = 2 ) and ( a = 8 ), then the eccentricity ( e ) is calculated as ( e = \frac{2}{8} = \frac{1}{4} ). Thus, the eccentricity is ( 0.25 ).
The eccentricity of a planet's orbit can be calculated using the formula e c/a, where c is the distance between the center of the orbit and the focus, and a is the length of the semi-major axis of the orbit.
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.
Eccentricity is only present in ovals and ellipses. A circle is present. The eccentricity of an oval or ellipse is how linear it is.
The eccentricity of the circle is zero.
The eccentricity of Psyche's orbit is 0.140
0.016710220 is the Earth's orbital eccentricity
"The old man's eccentricity was worrying." "Eccentricity is for the rich - the poor man is simply mad." "I am conducting a study of perceptions of eccentricity in different cultural groups." "Eccentricity should not be considered to be a negative aspect of personality, but rather a fascinating idiosyncrasy."
Of the planets in our solar system, Venus has the smallest eccentricity.
The eccentricity of a conic section is a measure of its deviation from being circular. An eccentricity of 1 indicates a parabola, meaning the curve opens indefinitely and does not close back on itself, unlike ellipses (eccentricity less than 1) or hyperbolas (eccentricity greater than 1). Therefore, a conic section with an eccentricity of 1 represents a parabolic shape.
