(Superman) What would happen if Superman where to be locked in a kryptonite cage and then flown into the sun?

Superman lives due to a variety of outcomes:

* On certain occasions extreme exposure to solar energy has given Superman the ability to quickly overcome the dangerous effects of krypotnite. As he draws closer to the sun, he gains the strength to break free.

If he cannot gather enough energy to break out... 

* Superman has been shown to be able to enter the sun and survive. Kryptonite isn't known to survive such extreme conditions. Depending on which area of the multiverse you're in, it will either **A.** Turn into black kryptonite, allowing superman and his evil clone to easily break free or **B.** Melt.

If somehow the sun doesn't alter the cage...

* Superman has a long life span. At least a million years long. Kryptonite's half-life is substantially shorter than that. The cage's ability to harm superman will gradually reduce over time, and his  powers will be restored.

If somehow the same solar energy that makes pieces Krypton poisonous to its former native inhabitants indefinitely prolongs its decay...

* Certain instances of Superman have been known to become immune to Kryptonite after constant exposure from villain after villain getting their hands on a piece. Long term exposure to the cage speeds up the process, and he breaks free with one less weakness.

If this immunity never develops because his exposure is constant...

* Superman is saved by Batman, because Batman has prepared for everything. *Everything.*
