[Superman] Why doesn't he just throw Doomsday into space?

So Doomsday can survive in deep space, so he wouldn't die and subsequently adapt to the situation. He's also incapable of flight, and doesn't seem smart enough to figure a way out of deep space. Superman, for his part, has been shown as capable of throwing very heavy things into space. He's also shown grappling with Doomsday, so obviously he *can* get a grip on the monster. Wouldn't throwing him into space be the most efficient way to end the conflict?

He tried. Multiple times.

The thing is, when you have to grab someone that's bigger stronger, faster than you, thrashing around, and covered in spikes, it's kind of hard to get, much less keep, a grip on it to throw it into space.
