What's a jump drive? The only method of travel like that were the intersystem gates, and they were massive ans stationary, certainly not capable of being mounted on a single snub ship. Even with cryonics, how is a single snub going to travel light years without losing power or supplies?
Also, as I recall, Sol was part of Daam K'Vosh territory. The Slomon K'Hara destroyed it after the humans had been judged unworthy after the war or something along these lines.
