WASP-103b is agaseous exoplanet, more specifically ahot Jupiter, located in theHercules constellation orbiting the starWASP-103. It has anoval shape, similar to that of arugby ball, thanks to the force of gravity exerted by its star. It is the first exoplanet to have a deformation detected.
It is 1.5 times moremassive, almost twice as large and twenty times hotter thanJupiter; These data suggest that WASP-103b has an interior structure similar to that of said planet. Its orbit lasts in 22 hours,[1] since it is located 0.01987astronomical units from its star, a fact that also gives it itsoval shape. Despite being very close to itssun, it seems to be moving away from it, instead of getting closer, giving rise to the theory that it is abinary system, or that the orbit of the exoplanet in question iselliptical.[2][3] Orbital decay was not detected by 2020.[4]
