Suppose my race wants to reach Earth, but due to the narrow reentry corridor of Earth's atmosphere, are currently hanging out on Pasiphae, a moon of Jupiter. Due to space being in constant motion, the planets and moons all having deteriorating, exclusive orbital rates, and having no fixed point of reference to gauge ones movement on, how is it possible to vector in an approach pattern for someone without our maps or navigation format?
Also, wtf is scrapple made of? It looks like pig intestine.

If they figured out intersteller travel but haven't figured this one out, they don't deserve to invade Earth.

Exactly, they'll probably adapt whatever system they used to get in and out of their own atmosphere (we can assume it's likely they mucked about closer to home before trying to invade Earth).
Renguard is a wonderful initiative

Supporters of Proposition 8 will argue California does not discriminate against gays, as the current law allows them to get married - as long as they wed a partner of the opposite sex.

hey, why exactly are you aliens trying to make the goal from all the way over there at Pasiphaë? Why worry about atmospheric entry NOW?
How are your alien spaceships constructed? Hopefully if you aliens are half-decent, you will have 1 big ship along with several smaller landing craft for scout/exploration purposes that can be launched individually? If not, you suck at making spacecraft lol.
So why don't you divide up your problem now.
1) Find Earth first and hold orbit. Now that I think of it, fellow human Dover's post makes sense. The closest star system to us is so many billion lightyears away. So if you aliens could find our solar system, you can most certainly use any onboard telescopes and other systems you have and find Earth. Then plot a course to it.
2) then worry about entering the atmosphere with the smaller craft you hopefully have onboard!
I will help you aliens more if I wasn't so sick atm...I could take my cool spacecraft book outta my closet and try to tell you something about plotting distances and re-entry and what not...haven't read it in a while though.
