An ellipse have two focal points.
The two central points of an ellipse are officially known as the foci (plural of focus).
it has somethign to do with Washington DC
foci
Basically a circle has a constant radius throughout and an ellipse does not.a circle has a constant radiusan ellipse has two foci. they are at either end of the ellipse
Earth's orbit is an ellipse; the Sun is at one of the ellipses focal points. (The other focal point has no astronomical significance.)
Earth orbits the Sun in an ellipse; the Sun is in one of the ellipse's focal points. The ellipse's shape, in this case, is quite close to a circle. The average distance from Earth to Sun is about 150 million kilometers.
The orbits of any object orbiting any other object is an ellipse. The central object (the Sun, in the case of the Earth) is in one of the focal points of the ellipse.
What are two points inside a ellipse
The planetary orbit around the sun is the path which planets follow.This path is elliptical in shape and the Sun lies at one of the focal points of the ellipse.
The same as planets - they move around the Sun in ellipses, the Sun being in one of the focal points of the ellipse. Read about Kepler's Laws for more details.

The two foci are necessary to define the location of an ellipse, but the shape depends on the eccentricity, which is related to the lengths of the two axes.
yes
The simple answer is that an ellipse is a squashed circle.A more precise answer is that an ellipse is the locus (a collection) of points such that the sum of their distances from two fixed points (called foci) remains a constant. A circle is the locus of points that are all the same distance from a fixed point. If the two foci are moved closer together, the ellipse becomes more and more like a circle and finally, when they coincide, the ellipse becomes a circle. So, a circle is a special case of an ellipse.
Insert two pins [they become the two focal points] vertically into a piece of paper or two nails into the ground. Fasten two ends of a thread or string, making sure that when you are finished the loop of string will easily loop around the pins. Loop the string around the pins. Now take a pencil or marker and mark the ellipse out on your surface keeping the string taught.
Ellipse has no sides and
