European Space Agency’s Cheops Mission Discovers ‘Hot Jupiter’ WASP-189 b

The European Space Agency has discovered a new exoplanet. The new exoplanet is named WASP-189 b. The discovery was made by the ESA’s Cheops mission. Cheops is a space telescope. It was launched by the ESA in December 2019. Its objective is to map the known exoplanets in the solar system. According to the ESA, WASP-189 b is one of the hottest and most extreme solar planets ever discovered. It is also called ‘ultra-hot Jupiter’ because it appears like Jupiter. As the name suggests, it is a gas giant just like the solar system’s Jupiter. The new exoplanet is approximately 20 times closer to its host star than Earth is close to the Sun.

WASP-189 b takes 2.7 days to complete one full orbit of its host star. According to the researchers, the ‘hot Jupiters’ orbit much closer to their host star. This is the reason why they are extremely hot. Researchers said that the new exoplanet is extremely hot. It has a temperature of about 3,200 degrees Celsius. This makes it clear that the just discovered exoplanet is inhabitable. Researchers noted that there are very few planets that are known to exist around stars with extremely hot temperatures. The WASP-189 b is the brightest hot Jupiter. Researchers observed the celestial body as it passed behind and in front of its star.

The latest finding shows Cheops’ ability to discover the secrets of the solar system. Researchers used the telescope to observe WASP-189 b as it passed behind its host star. They measured its brightness and temperature as well. They concluded that WASP-189 b is one of the hottest planets. It is not like any of the eight known planets of the solar system. WASP-189b was first detected by scientists in 2018. The ESA’s telescope provided the first picture of the planet. The ESA said that the first result from the Cheops is exciting. It added that the Cheops mission is living up to expectations.
