Well, honey, determining the eccentricity of an object or orbit involves taking the ratio of the distance between its foci to its major axis length. So basically, you divide the distance between the two “centers” by the length of the longest part. It's that simple, dear. Just a little math magic to figure it out.

Which ellipse resembles earth's orbit?
Earth's orbit around the sun is best represented by an ellipse with a very small eccentricity, which means it is almost a perfect circle. The eccentricity of Earth's orbit is about 0.0167, making it very close to a circular shape.
What is the eccentricity of orbit in earth days?
The eccentricity of an orbit is not measured in days. The excentricity is a numeric value between 0 (for a perfect circle) to 1 (for an extremely prolonged elipse).The eccentricity of an orbit is not measured in days.

How can you tell which planet has the most circular orbit?
You can look through a list of the planets' orbits to see which one has the smallest eccentricity, and the answer is Venus, 0.006787. But if you are an astronomer wanting to find it out by observing the planets in the sky, you need to have five accurate positions for each planet, spaced out across a good fraction of the orbit, and then you can calculate the 'elements' of the orbit. One of the elements is the eccentricity. The eccentricity and the semimajor axis determine the shape and size of the orbit. Then there is the longitude of perihelion, which sets the orientation of the major axis of the ellipse. Two more are the inclination of the plane of the orbit to the plane of the Earth's orbit, and then the longitude of the ascending node, which defines the line of intersection of the two planes. Finally the longitude at the Epoch and the date of the Epoch are required because they set the starting conditions for the model.
If an asteroid is in an elliptical orbit about the Sun with the Sun almost at the center of the ellipse what would the eccentricity of the ellipse be?
All natural orbits are ellipses. We can force an artificial satellite into a spherical orbit, but it won't STAY there without occasional adjustments. The "primary body" - in this case, the Sun - is at one of the two focuses (foci) of the orbit. If the focus is very close to the "center" of the ellipse, then the eccentricity of the orbit (how much it varies from a perfect circle) is close to zero.
Planet with the least circular orbit?
The eccentricity value measures how non-circular an orbit is. The planets in decreasing order of eccentricity with their approximate eccentricity values are: # Pluto: 0.25 # Mercury: 0.21 # Mars: 0.093 # Saturn: 0.056 # Jupiter: 0.048 # Uranus: 0.047 # Earth: 0.017 # Neptune: 0.0086 # Venus: 0.0068
How do you determine which of two orbits is most elliptical?
You can determine which of two orbits is most elliptical by comparing the eccentricities of the orbits. The orbit with the higher eccentricity is more elliptical. Eccentricity measures how stretched out an orbit is, with a value of 0 indicating a perfectly circular orbit and a value closer to 1 indicating a highly elliptical orbit.
Why isn't the eccentricity of an orbit never greater than one?
An orbit can have an eccentricity greater than 1. It is the type of orbit that an object has when it comes in from outer space at high speed on a single encounter with the Sun before it disappears off into interstellar space again. This type of orbit is called a hyperbola, and it is the fourth type of conic section along with the circle, the ellipse and the parabola.

What is the eccentricity of Venus?
The eccentricity of Venus' orbit around the Sun is approximately 0.0067. This value indicates how elliptical the orbit is, with 0 being a perfect circle and 1 being highly elongated. Venus has one of the least eccentric orbits among the planets in our solar system.
What planet has the least distance between the two Foci of its elliptical orbit?
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.

Which equation should be used to find the eccentricity of the earths orbit?
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.
