Planets That Can Dwarf Stars

The video explores the diversity of star systems, questioning if planets can be larger than their host stars. It explains the mass and volume differences in stars, highlighting neutron stars and white dwarfs. The video discusses exoplanets around neutron stars and white dwarfs, including the remarkable WD1856B system. It also examines the challenges of finding large planets around main sequence stars, focusing on VHS 1256-1257. Finally, it identifies the largest known exoplanets, such as GQ loopy B, and considers the possibility of planets larger than their stars.
