HD 100546 b: 6.9 +2.7 −2.9: Largest exoplanet in the NASA Exoplanet Archive, although because of flux from the planet and the disk that are superimposed, the exact size of this planet cannot be determined and the emitting area has this size, composed of the planet and most likely its disk too, and is not to be mistaken as a single planet radius.Over time, it will shrink to the size of Jupiter.
