Jupiter moon question

What is Jupiter's most distant moon? From the viewpoint of my
backyard with Jupiter at closest opposition, at zenith at midnight,
how many degrees maximum distance is it from its mother planet?

Most distant moon is a small bit of rock called S2003 J2
at a distance of about 30,291,000 km from Jupiter. That's
about 0.2 AU (Astronomical Units).

Jupiter's orbital radius is about 5.2 AU, and the Earth's
is 1 AU.

That should be enough information for you to do the math.

Or a rough sketch. Looks to be about 5 degrees separation,
more food for contemplation while enjoying the night sky.

A NASA website has a slightly different value for the
orbital radius of S2003 J2:

http://nssdc.gsfc.nasa.gov/planetary...ansatfact.html

It lists it as 28570x10^3 km, or about 0.191 AU.

The closest approach of Jupiter to the Earth would be
about 5.2 - 1 = 4.2 AU. This would give an angular
separation (center to center) of Jupiter and S2003 J2
of

atan(0.191/4.2) = 2.6 degrees
