TOI-3757 b is a gas giant exoplanet located in the constellation of Auriga^[1] 578 light years, or 177 parsecs, away from Earth.^[2] It is well known for having a low density; as a result, it has been monikered the 'fluffiest planet ever'^[3] and the 'marshmallow world'.^[4] Its density is 0.27+0.05
−0.04 g/cm³,^[2] so low that it could float in a bathtub large enough to hold it.^[5] It is the least dense planet discovered around a red dwarf star, and also has the lowest metallicity of an gas giant around a red dwarf.^[6]^[2]
