Anything stopping Palpatine and Vader combining their powers to paralyze Supes??
But if we're talking comic supes, he is an overpowered tool. But the animated Supes defo could not take out the GE. He barely took a shot from the Watchtower's laser beam, so an SD should pretty much destroy him and the DS would be overkill.
Anyway thats all assuming Supes even has powers in the SW Galaxy.
Also worth noting that Superman once got punched with the equivalent mass of planet Earth right in the jaw and only suffered a bloodied lip. He appeared to be KOed but he was playing Possum.
The Death Star would be next to useless against Superman, in fact the Empire would be smart to try to scrap it and use its spare parts to make a fleet of smaller ships that might have a slim chance of being effective against him.

Neutrinoes are particles that can pass through the entire planet earth without actually interacting with anything because they have no charge. Very rarely, maybe a dozen (recorded) times a day, a neutrino will strike a water molecule in the antarctic and the extensive network of sensors installed there will pick up the resultant flash of light. You are currently being bombarded with neutrinoes and experience literally no effect.
In a supernova, so many neutrinoes are generated that the outer portion of the star is blown apart.
This is my favorite astronomy fact. [SPOILER - highlight to read]: why is gideon banned again?
