The discovery could challenge our theories of how gas giants like Jupiter form.
Though gas giants have been discovered around M dwarf stars before, none of them have been discovered orbiting such a low mass example of this class of star-like TOI-5205.
Current planet formation models suggest that to birth a gas giant it takes material equivalent to 10 times the mass of Earth. This first forms a rocky core and this core goes on to accumulate gas to form the disc to grow a giant planet. This process has to occur quickly, however. To picture how unbalanced this system is to planetary systems that astronomers expect, imagine our star the sun squashed down to the size of a grapefruit. That size reduction would mean the largest gas giant in ourThe TOI-5205 system is more like a pea orbiting a lemon.
