WASP-103b is a gaseous exoplanet, more specifically a hot Jupiter, located in the Hercules constellation orbiting the star WASP-103. It has an oval shape, similar to that of a rugby ball, thanks to the force of gravity exerted by its star. It is the first exoplanet to have a deformation detected.

Features
editIt is 1.5 times more massive, almost twice as large and twenty times hotter than Jupiter; 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 0.01987 astronomical units from its star, a fact that also gives it its oval shape. Despite being very close to its sun, it seems to be moving away from it, instead of getting closer, giving rise to the theory that it is a binary system, or that the orbit of the exoplanet in question is elliptical. [2] [3] Orbital decay was not detected by 2020.[4]
