Discovery and observations
WASP-189 b was first discovered in 2018.[5] In 2020, astronomers used CHEOPS to observe it. Based on a passage behind its host star (occultation) the planet's brightness could be measured and the temperature was estimated to be 3,200 °C (5,790 °F; 3,470 K). Based on a passage in front of its host star (transit) the radius is 1.6 times the radius of Jupiter.[1][2][4] Its atmosphere contains titanium oxide, and also contains metals such as chromium, magnesium, vanadium and manganese.[6]
