0.016710220 is the Earth's orbital eccentricity
Venus is closest to the Earth in size and mass. Its diameter is around 95% of Earths, while its mass is around 81.5% of Earths.
Mars
Mars
A planet called Kepler 186f, in the constellation Cygnus, is the same size as the Earth and it is similar to Earth in looking to. Venus is only slightly smaller than Earth and is the closest in size to it in our solar system.
The eccentricity of the Earth's orbit is currently about 0.0167; that rounds to zero.
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
More eccentric.
Saturn has an eccentricity of 0.054 which is almost exactly the same as moon's eccentricity of 0.055. They differ by 1.5%. This makes Saturn's orbit the closest approximation of the lunar orbit.
0.016710220 is the Earth's orbital eccentricity
Venus is closest to the Earth in size and mass. Its diameter is around 95% of Earths, while its mass is around 81.5% of Earths.
The eccentricity of Earth's orbit around the Sun is approximately 0.0167. This value indicates how elliptical or circular the orbit is, with 0 being a perfect circle and 1 being a straight line. A lower eccentricity value like Earth's means the orbit is nearly circular.
The Earth has an eccentricity of 0.01671123. Where 0 is a perfect circle, and 1 is a parbola. So by that it has a low eccentricity.
Venus is often compared as Earth's "sister planet", being similar in size and internal composition.
The eccentricity of the Earth's orbit is approximately 0.0167. This value represents the deviation of the Earth's orbit from a perfect circle. The eccentricity affects the Earth's distance from the Sun, with the closest point being perihelion and the farthest point being aphelion.
Mars
The Earth is to the Moon as a planet is to its moon. So, if we're talking about a satellite orbiting a planet, then the planet would be analogous to the Earth, and the satellite would be analogous to the Moon.
