Homework Statement
Find maximum possible aphelion distance for a Kuiper Belt comet with an orbital period of 216 years?
What is the eccentricity of this orbit?
What prevents a periodic comet from following this precise orbit?
Homework Equations
perihelion = a(1-e)
aphelion = a(1+e)
2a = perihelion + aphelion
P^2=a^3
The Attempt at a Solution
P^2=a^3
(216)^2 = a^3
a = 36 AU (semi major axis)
From here, I'm not sure where to go because I don't know the eccentricity, perihelion or aphelion distance
