Comets Have Highly Eccentric Orbits, with Eccentricities of 0

Essay

Comets have highly eccentric orbits, with eccentricities of 0.95 to 0.99 being common.Suppose a certain comet has an eccentricity of 0.99.If the semimajor axis of its orbit is 2,500 AU, what will be its distance at perihelion and at aphelion? Is this most likely a Kuiper Belt object or an Oort Cloud comet? (Note: For an ellipse, a(1+ e) is the distance from one focus to the farther edge of the long axis and a(1 -e) is the distance from the same focus to the closer edge of the long axis.)
