As A Degenerate Ellipse
A line segment can be viewed as a degenerate case of an ellipse in which the semiminor axis goes to zero, the foci go to the end points, and the eccentricity goes to one. As a degenerate orbit this is a radial elliptic trajectory.

Famous quotes containing the words degenerate and/or ellipse:
“When I think of some of the Persians, the Hindus, the Arabs I knew, when I think of the character they revealed, their grace, their tenderness, their intelligence, their holiness, I spit on the white conquerors of the world, the degenerate British, the pigheaded Germans, the smug self-satisfied French.”
—Henry Miller (1891–1980)
“The ellipse is as aimless as that,
Stretching invisibly into the future so as to reappear
In our present. Its flexing is its account,
Return to the point of no return.”
—John Ashbery (b. 1927)
