Exoplanet Radio - Ep. 22: HAT-P-67b: The Largest Known Exoplanet

From August 17, 2023. According to the NASA exoplanet archive, HAT-P-67 b holds the distinction of being the largest exoplanet in terms of size.  With exoplanet classification, one always needs to be careful - especially when it comes to size and mass - because there is a fuzzy boundary with large planets where if they become too large, they are considered a brown dwarf star.  This is a body that almost made it to star status but doesn’t have enough mass or material for nuclear fusion to take place.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
