On the Earth, the tides in the oceans are principally the result of the mild pulls that happen while the Moon orbits our planet. The same thing happens with the Sun too, however, its long distance from the Earth prevents it from causing significant deformations in the earth's surface.
Wasp-103b has almost double the size of Jupiter and its mass is 1.5 times bigger. Moreover, it orbits its host star within less than a day.
According to the astronomers, this kind of proximity might provoke enormous tides, which deform the exoplanet and cause it to have its characteristic spread-out shape.
Now, the people in charge of this discovery hope to continue unveiling more features about the unique exoplanet, and for this reason, they expect especially to utilize the information that the spatial telescope James Webb might collect.
