the eccentricity of comet tempel-tuttle ia 0.9055
The eccentricity of Halley's comet is approximately 0.967, which is quite high compared to other solar system objects. This high eccentricity means that its orbit is very elongated, taking it from the outer solar system to the inner solar system and back every 76 years.
0.995. High excentricities (approaching 1) are quite common for comets.
Elliptical paths, just like planets. Typically, but not always, with greater eccentricity.
Halley's Comet has an orbital period of approximately 76 years. Since it was last observed in 1986, it is expected to return to the inner solar system and be visible again around 2061.
The eccentricity of Psyche's orbit is 0.140
stupid old comet encke doesn't have any eccentricity at all!

All orbits are ellipses; this is true for both planets and for comets. Cometary orbits are somewhat extreme ellipses, where the difference between the perihelion (closest to the Sun) is very different from the aphelion (farthest from the Sun) distance. This difference is called "eccentricity". Planets have relatively low eccentricity; for Earth, for example, the eccentricity is only 3%. Some comets don't have an "orbit" at all. An "orbit" implies that the comet will eventually come back. But some comets are "hyperbolic"; their paths aren't an ellipse, but a hyperbola. A hyperbolic comet is a one-time visitor to the solar system; it has fallen in from interstellar space, and will be going back out to interstellar space.
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.

Eccentricity is only present in ovals and ellipses. A circle is present. The eccentricity of an oval or ellipse is how linear it is.
The eccentricity of the circle is zero.

"The old man's eccentricity was worrying." "Eccentricity is for the rich - the poor man is simply mad." "I am conducting a study of perceptions of eccentricity in different cultural groups." "Eccentricity should not be considered to be a negative aspect of personality, but rather a fascinating idiosyncrasy."
