Mega-Earths: The Planets That Shouldn’t Exist

🔥 Some planets are so massive that their existence challenges the models meant to explain how planets form. 🌌 Mega-Earths occupy a puzzling boundary between rocky worlds and gas-rich planets but what makes these unusually large, high-mass planets so difficult to account for? This video examines how astronomers identify and classify mega-Earths, what their measured masses and radii can and cannot reveal about their interiors, and why their formation remains a demanding problem in planetary science. 🪐 Explore the evidence, the competing interpretations, and the limits of current observations without reducing a complex question to a single easy answer. If you are interested in exoplanets, planetary structure, and the physics of planet formation, this is a chance to see why these worlds continue to provoke debate. 🔭 💬 Which aspect of mega-Earths do you find most intriguing: their composition, their origins, or the difficulty of observing them?
