Astronomers are studying the recently discovered exoplanet WASP-189b, considered, in their own words, “the most extreme planet ever seen”. Researchers from the University of Bern are using the CHEOPS space telescope to conduct a detailed study of the exoplanet. WASP-189b has a massive surface temperature of 3,200°C.
“Based on the observations using CHEOPS, we estimate the temperature of WASP-189b to be 3,200 degrees Celsius. […] Planets like WASP-189b are called ‘ultra-hot Jupiters’. Iron melts at such a high temperature and even becomes gaseous. This object is one of the most extreme planets we know so far”, said Monika Lendl, who led the study.
WASP-189b has one side with permanent day time and the other with permanent night, according to the researchers.
“The WASP-189 system is 322 light-years away and located in the constellation Libra”. The planet is on the orbit of HD 133112, one of the hottest stars with a planetary system, according to Mirror.co.uk.
“WASP-189b is especially interesting because it is a gas giant that orbits very close to its host star. It takes less than 3 days for it to circle its star, and it is 20 times closer to it than Earth is to the Sun.”
