If he was moving fast enough, to maintain orbit or break it, he would be going tremendously fast. He has a pretty good boost from the momentum of the Normandy when it's destroyed. He could have been moving fast enough to remain in orbit, maybe break from it if the Normandy was trying to escape.
His speed would have to be enormous to pass through the atmosphere and not land.
As for "frying" from exposure, it would be safe to assume his armor is to some degree insulated well enough to manage such exposure, much like a modern day space suit. I'm not sure if, after getting punctured, the suit would become totally useless against the sun. It would eliminate his insulation, but not the shielding of the physical suit itself.
If he does land on the planet, I would suggest that debris assaulted his suit, placing him into a vacuum and boiling some of the water from his blood into space. He then landed on the planet, already dead, perhaps on a snowdrift.
It sounds absurd on the face of it. If I knew more about how fluids boil in space, and if it were possible for them to "vent" as a result of punctures... it's total speculation.
Sort of fun trying to figure this out. I wouldn't guess Bioware actually calculated this in-depth, considering their lack of research in numerous other scientific areas.
All that said, there is in canon the established fact that there was considerable cellular degeneration.
Another thought (I figure people are ignoring me to continue their argument, but so what): If Shepard was tracking him, agents might have come in to find his body or rescue him after the Normandy was attacked. These agents may have been ambushed by Shadow Broker or Collector agents, and from there the body would pass through many hands. Or perhaps the Collector's themselves retrieved his body, put it in stasis, and it was stolen from them briefly by Cerberus agents or some other interested entity. It's ambiguous who found him first, or how.
One more thing that this resurrection adds to the story. It ties in the fact that the Reapers are able to extract knowledge and genetic material from vast numbers of beings, while killing them in the process. They preserve life through extinction, etc. They can actually use LESS than the Lazarus project has to revive Shepard.
