My mission is to find the aphelion.

I know that this is given by

[tex]r_{aph} = a(1+e)[/tex]

And I have used that

[tex]a = \frac{r_{per} + r_{aph}}{2}[/tex]

This gives me

[tex]r_{aph} = \frac{r_{per}(1 + e)}{1-e}[/tex]

and then I get that [tex]r_{aph} = 2988 AU[/tex]. This all seems very simple so what am I doing wrong?

The correct answer should be [tex]r_{aph} = 4698 AU[/tex]
