Jupiter-sized horror planet with 3,200C climate that vaporises metal is ‘one of most extreme ever found’
ASTRONOMERS have revealed details about one of the most extreme planets ever discovered.
Planet WASP-189b has surface temperatures of 3,200 degrees Celsius (5,792 degrees Fahrenheit), meaning it could vaporise you.
Researchers at the European Space Agency measured those extreme temperatures with the CHaracterising ExOPlanet Satellite (CHEOPS).
WASP-189b isn’t as hot as the Sun but it could still turn metals and rocks to gas in seconds.
It’s not in our Solar System so it’s known as an exoplanet.
The scary planet orbits its star every 2.7 days.

One side is always ‘day’ and the other is always ‘night’.
The planet is also huge, measuring 1.6 times the size of Jupiter.
Astrophysicist Monika Lendl from the University of Geneva said: “WASP-189b is especially interesting because it is a gas giant that orbits very close to its host star.
“It takes less than three days for it to circle its star, and it is 20 times closer to it than Earth is to the Sun.”

The planet’s host star is actually 2,000 degrees Celsius (3,600 degrees Fahrenheit) hotter than our Sun.
That makes it one of the hottest stars known to have planets orbiting it.
WASP-189b is 326 light-years away from Earth, which is too far away to observe directly.
However, CHEOPS was able to observe and learn more about its makeup by watching it transit its star.
Lendl said: “Only a handful of planets are known to exist around stars this hot, and this system is by far the brightest.
“WASP-189b is also the brightest hot Jupiter that we can observe as it passes in front of or behind its star, making the whole system really intriguing.”
The researchers now want to find out how the planet formed in the first place.
This study has been published in Astronomy & Astrophysics.
What is an exo-planet?
Here’s what you need to know…
- An exoplanet is a planet that is located outside of our Solar System and one that is orbitting its own star, like how Earth orbits the Sun
- They are very hard to see with telescopes because they are often hidden by the brightness of their star
- Nasa sent the Kepler space telescope into orbit with the purpose of finding Earth sized exoplanets that might support life
- Over 4,000 exoplanets have been discovered so far and more missions to find even more exoplanets are planned
- A good way to spot an exoplanet is to look for “wobbly” stars because a disruption to star light can indicate that a planet is orbitting it and therefore blocking out light on occasion
- Expoplanets are very common in the Universe and the more we find that look like Earth the closer we get to knowing if we’re not alone out there

The space agency finally set a date for its first proper crewed flight from US soil aboard a SpaceX rocket.
And, SpaceX blew up a Starship rocket tank on purpose last week during a dramatic “pressure test”.
