What is the name of the swamp planet where Yoda lives?

The story behind the answer

Dagobah is the remote swamp world where Yoda chose exile after the fall of the Jedi Order. Its dense fog, teeming wetlands, and rich life made it a perfect hiding place; the planet’s strong natural Force presence masked him from Imperial detection. It’s also where Luke Skywalker undergoes his Jedi training in The Empire Strikes Back, including the eerie cave imbued with the dark side that tests Luke’s fears.

Distractors: Dathomir is the red, misty home of the Nightsisters and Darth Maul’s people; Naboo is a civilized, verdant planet with Theed and underwater Gungan cities; Felucia is a psychedelic world of towering fungi, seen during Order 66 when Aayla Secura falls. None match the murky, uncharted bog world where the Grand Master lives in solitude.
