ELI5: If we die in space will our body still decompose or will it float around relativly uncomposed?

As in title, if you get detached from your ship in your suit and just keep floating away into nothingness, once you die will your body decompose (maybe from the bacteria that is naturally in the body) or will it stay relativly "untouched" and just float around?

Bacteria gets killed by the cold. There’s nothing to decompose you, but, freed of a suit (and perhaps regardless anyway) half of you is frizzling with pure solar energy cooking you up nicely, while the lee side freezes in the cold emptiness of space. 

I imagine micro abrasion from flying sand particles would eventually wear you down and in time I’m pretty sure you’d wind up getting sucked into a gravity well, perhaps eventually descending to the surface of whatever body that is, most likely being dealt with by whatever atmosphere exists there.
