## Homework Statement

Find the maximum (aphelion) distance from the Sun for extreme elliptical orbit. (Semi-Major axis = 26)

## Homework Equations

Eccentricity = Distance between foci/Length of major axis

Major Axis = 2 * Semi-Major Axis

Major Axis = Perihelion + Aphelion

## The Attempt at a Solution

Eccentricity = Distance / (26*2) = Distance / 52

Eccentricity of an elliptical orbit is between 0 and 1, 0 being a circle.

What eccentricity should I be using for an extreme elliptical orbit?

My best guess would be right under 1 (ex: 0.99) but I'm not sure if that makes sense. (Would it be too close to the sun?)

Then once I have the distance between the foci, I would do semi-major axis - 1/2 distance between foci, in order to get the perihelion. From there I can get the aphelion.
