Aschelan V
From Star Trek : Freedom's Wiki
Aschelan V is a planet located near the Demilitarized Zone where a Cardassian fuel depot is located.
In 2370, B'Elanna Torres reprogrammed the Cardassian missile Dreadnought to destroy the depot on Aschelan V. However, the missile again failed to reach its target, as one day after its launch it was swept into the Delta Quadrant by the Caretaker. There, it locked onto the similar planet Rakosa V, mistaking it to be Aschelan V. (VOY: "Dreadnought")
