What is the minimum eccentricity a ellipse can have?
What does eccentricity means? But a ellipse is a word i dunno, all i know is the ecllispe the minty mint i eat every day.
What is the distance from one of the foci of the ellipse from its center?
The length of the semi-major axis multiplied by the eccentricity.
What happens to the shape of an obit as eccentricity gets smaller?
As the eccentricity reaches zero the two foci merge together and the ellipse becomes a circle. If a is half the major axis of the ellipse, and e is the eccentricity, the distance between the foci is 2ae. For a planet the Sun occupies one focus and the other is vacant, so the Sun is a distance of ae from the centre of the ellipse. The minor axis is sqrt(1-e^2) times the minor axis, so for all the planets except Mercury the minor axis is more than 99½% of the major axis. The best way to draw an orbit is to ignore this small difference and draw a circle, and then place the Sun at the right distance off-centre.
What is the minimum eccentricity an elipse can have?
the minimum would be a zero. and a eccentricity of zero would be a circle because if it's a zero, you only have one point because there is no focal distance. if you have only one point to connect, it would be a circle. on the other hand, the maximum would be one; a line. because eccentricity is in a fraction/decimal form. the person before me wrote 7. that is not humanly possible, because that would mean a fraction like 700/100. and how can the focal distance be grater than the major axis?
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.

Which ellipse resembles earth's orbit?
The Earth's orbit is close to being a circle. So, the ellipse is one with a small "eccentricity".
What is the distance from one of the foci of the ellipse from its center?
The length of the semi-major axis multiplied by the eccentricity.
When is an ellipse very accentrie?
An ellipse is very eccentric when its foci are far apart.The closer one focus is to the other, the less eccentric the ellipse is.When when both foci are the same point, the eccentricity is zero, and the ellipse is a circle.

Define the focus and the eccentricity of an ellipse?
A circle is perfectly round, and has one center. An ellipse is like a circle with TWO "centers", and each "center" is called a "focus". The plural of "focus" is "foci". Take a piece of string and tie a loop in each end. Put a pin through the loops, and hold it still in the center of the circle. Place the tip of your pencil at the center of the string, and you can draw a circle by keeping the string taut. Now take TWO pins, and put one pin at each end of the string; place the pins at some short distance apart, and hold them there. Place your pencil and draw, and the shape you draw will be an ellipse. The two pinpoints are the focuses, or foci, of the ellipse. Eccentricity is a measure of how far the ellipse varies from a circle. An ellipse with an eccentricity of zero _IS_ a circle, while an eccentricity of 1.0 is a straight line, with that string stretched out straight. In astronomy, every natural orbit is an ellipse.
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.
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.
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.
Which eccentricities represent most elongated ellispe?
The elongation of the ellipse increases as the eccentricity increases from 0 to 1. For eccentricity zero it's a circle, and with eccentricity 1 it's a parabola. They are all a class of curve called a conic section. If you can find a torch (flashlight) that produces a conical beam, shine it directly at the wall and you get a circle. Shine it at an inclined angle and you get an ellipse. If the angle is increased so that one side of the cone is parallel to the wall, you see a parabola on the wall. Any more of an angle and you get the 4th conic section, a hyperbola.
What is also known as the semimajor axis?
The major axis of an ellipse is its longest diameter, a line that runs through the center and both foci, its ends being at the widest points of the shape.The semi-major axis is one half of the major axis, and thus runs from the centre, through a focus, and to the edge of the ellipse. It represents a "long radius" of the ellipse, and is the "average" distance of an orbiting planet or moon from its parent body.
