The larger objects is at one of the two foci. For example, the Sun is at one of the foci of Earth's elliptical orbit. If the eccentricity of an ellipse is large, the foci are far apart. If the eccentricity is small, the foci are close together.et's take a look at the mathematical definition of an ellipse. First, place two points on a plane; these will be the foci of the ellipse. Now, pick a distance that is larger than the distance between the two foci. We'll call that distance 2a, for reasons that will become clear in a minute.
The vertices are some fixed distance a from the center. The line going from one vertex, through the center, and ending at the other vertex is called the transverse axis. The foci of an hyperbola are inside each branch, and each focus is located some fixed distance c from the center. (This means that a < c for hyperbolas.) The values of a and c will vary from one hyperbola to another, but they will be fixed values for any given hyperbola. ADVERTISEMENT.
