Proplyd 133-353 is possibly the largest known exoplanet. This celestial body is likely a sub-brown dwarf/rogue planet. Proplyd 133-353 is likely not able to fuse deuterium disqualifying it from being a brown dwarf, the mass limit for deuterium fusion is slightly over 13MJ[1] and Proplyd 133-353's mass is likely under this threshold. Proplyd likely has a photoevaporating disk as shown in the graphic on the right. Proplyd 133-353 is also a very young exoplanet with an age of just 500,000 years making it one of the youngest exoplanets known.[2]
Location[edit]
Located in the Trapezium Cluster, Proplyd 133-353 is approximately 1,265.5 light years away.[2]
