A planet-hunting satellite has observed one of the hottest exoplanets yet discovered, with surface temperatures so high they could turn metals to gas.

The European Space Agency’s (ESA) Characterising ExOPlanet Satellite (CHEOPS) spied the extreme exoplanet in question – which is named WASP-189b – some 326 light-years away from Earth.

Classified as a so-called ‘hot Jupiter’, the planet’s surface temperatures reach 3,200 degrees Celsius (5,792 degrees Fahrenheit). While only about half the searing surface temperature of our sun (6,000 degrees Celsius or 10,832 degrees Fahrenheit), it is still one of the most extreme planets ever discovered by the ESA, or by mankind in general.

Roughly 1.6 times the size of Jupiter, WASP-189b boasts an orbit of just 2.7 days around its star, with permanent day and night on opposite sides of the planet. (RT)
