Which celestial body did the mattress fall the fastest?

What are the options and what are the different celestial bodies?

Explanation:

you can't expect someone to fully answer a question where they need more information to answer it in the first place> if you edit your answer, you should be able to add those needed pieces of information to the question!

that or you might get flagged for having a confusing or incomplete answer, i wouldn't do that i'm just warning you for future reference!

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
