A Red Giant.
Explanation:
Once the Sun completes its main sequence stage in about 4.5 Billion years it would have burned all of its hydrogen into helium. After the main sequence stage the Sun will rearrange itself, its core will shrink and its outer layers will expand. This stage is called the Red Giant stage in which the Sun will burn Helium into Carbon.
Since fusing Helium to Carbon is a very unstable process. This means that the Red Giant Sun will be much more denser than its main sequence stage. This stage lasts for another 100 million years until the Sun has no more Helium to fuse into Carbon.
