An article published in the journal “Astronomy & Astrophysics” reports a study of the exoplanet Wasp-103b that offers evidence of its oval shape. A team of researchers used data collected by ESA’s CHEOPS space telescope to have the accuracy needed to assess this gas giant’s anomalous shape. It’s due to its star’s powerful tidal forces, as the star is a bit larger and more massive than the Sun, on this planet due to their proximity. In fact, Wasp-103b is so close to its star that its year lasts a little less than an Earth day.
