There's an alternate approach that would match the existing dialog:
If you've got engines with the power to push a 190,000 metric ton ship to high percentages of light than those engines can easily push you out of orbit and out of the system.
But with damaged engines, it may turn out that you can only do one
such "push" - namely, the one that will slow you down from your high relativistic speed to orbit around Delta Vega.
to the speed that will take you to civilization is a massive effort in real world terms, and quite possibly no walk in the park for damaged impulse engines, either. Quite realistically, the delta-vee you have available might be capable of taking you all the way to Earth, or
to orbit around Delta Vega, but not both.
