It is 0.056, approximately.
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.
The orbit of Earth around the Sun is an ellipse, but it is nearly circular, with an eccentricity of about 0.0167. In comparison, the roundness of an ellipse depends on its eccentricity; a perfect circle has an eccentricity of 0. Therefore, if "ellipse 1" has a higher eccentricity than Earth's orbit, it would be less round than Earth's orbit; otherwise, Earth's orbit is rounder.
It takes 10,832 Earth days to complete one orbit around the Sun.
Mercury has an eccentricity of about 0.206, which means its orbit is more elliptical than circular. This eccentricity causes Mercury's distance from the Sun to vary significantly during its orbit, leading to temperature extremes on the planet's surface.
Venus takes about 225 Earth days to complete one orbit around the sun. Its orbit is almost circular, with very little eccentricity compared to other planets.
The eccentricity of the Earth's orbit is currently about 0.0167; that rounds to zero.
The Earth's orbit is almost circular. Technically, the "eccentricity" of the orbit is about 0.0167.
The eccentricity of Neptune's orbit is approximately 0.009. This means that Neptune's orbit around the Sun is very close to being a perfect circle.
The Earth's orbit is almost circular. Technically, the "eccentricity" of the orbit is about 0.0167.
The eccentricity of Saturn's orbit is 0.053, which means that its orbit around the Sun is slightly elliptical rather than a perfect circle. This eccentricity causes Saturn to be closer to the Sun at certain points in its orbit and farther away at others.
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.
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.
Are you asking what the length of Saturns's orbit is?
The orbit of Earth around the Sun is an ellipse, but it is nearly circular, with an eccentricity of about 0.0167. In comparison, the roundness of an ellipse depends on its eccentricity; a perfect circle has an eccentricity of 0. Therefore, if "ellipse 1" has a higher eccentricity than Earth's orbit, it would be less round than Earth's orbit; otherwise, Earth's orbit is rounder.
100,000 and 400,000 years, caused by changes in the shape of earth's orbit around the sun.
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.
