The eccentricity of an ellipse is a number related to how "egg-shaped" it is ... the

difference between the distance through the fat part and the distance through the

skinny part. That's also related to the distance between the 'foci' (focuses) of the

ellipse.

The farther apart the foci are, the higher the eccentricity is, and the flatter the ellipse is.

Comets have very eccentric orbits.

When the two foci are at the same point, the eccentricity is zero, all of the diameters

of the ellipse have the same length, and the ellipse is a circle. All of the planets have

orbits with small eccentricities.

If the pins in the following diagram were placed closer together the eccentricity of the ellipse being constructed would?

Assuming that the pins represent the foci, the answer is that the eccentricity would be reduced.


How does the shape change with increasing eccentricity?

As the eccentricity of a shape increases, the shape becomes more elongated or stretched out. For example, an ellipse with a higher eccentricity will look more like a stretched circle. In general, as eccentricity increases, the shape will deviate more from its original form and become more elongated.


What planets has the least distance between the two foci of its elliptical orbit?

Pluto Thanks for the answer! Unfortunately I meant to restrict the question to the 5 planets visible with the unaided-eye. Mercury, Venus, Mar, Jupiter & Saturn (excluding Earth). My mistake. Then again, perhaps its the planet furthest from the sun would have the greatest deviance from a perfect circular orbit. In that case, of the classical 5, it might be Saturn.


How can one determine the eccentricity of an object or orbit?

The eccentricity of an object or orbit can be determined by calculating the ratio of the distance between the foci of the ellipse to the length of the major axis. This value ranges from 0 (perfect circle) to 1 (highly elongated ellipse).


Which planet has an orbital eccentricity most like the orbital eccentricity of the moon?

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.

How does the eccentricity of an ellipse change as the foci get closer together?

As the foci of an ellipse move closer together, the eccentricity of the ellipse decreases. Eccentricity is a measure of how elongated the ellipse is, defined as the ratio of the distance between the foci to the length of the major axis. When the foci are closer, the ellipse becomes more circular, resulting in a lower eccentricity value, approaching zero as the foci converge to a single point.


What is the formula for eccentricity?

eccentricity = distance between foci ________________ length of major axis


What will happen to the eccentricity of an ellipse as the distance between the foci increases?

the eccentricity will increase.


When the distance between the foci of an ellipse is increased the eccentricity of the ellipse will?

When the distance between the foci of an ellipse increases, the eccentricity of the ellipse also increases. Eccentricity is a measure of how much an ellipse deviates from being circular, calculated as the ratio of the distance between the foci to the length of the major axis. As the foci move further apart, the ellipse becomes more elongated, leading to a higher eccentricity value. Therefore, an increase in the distance between the foci results in a more eccentric ellipse.


What is the eccentricity of an ellipse in which the distance between the foci is 2 centimeters and the length of the major axis is 5 centimeters?

The eccentricity of that ellipse is 0.4 .


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.

What is the FOCI of a circle?

A circle is an ellipse with an eccentricity of zero. Both foci of that ellipse are at the same point. In the special case of the circle, that point is called the "center".
