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
It 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]
