Venus is the second planet from the Sun and is the hottest planet in our Solar System. But it is not the hottest planet in the universe. That honor belongs to KELT-9b, a distant exoplanet located 670 light-years away from Earth. KELT-9b has a surface temperature of 7,800 degrees Fahrenheit, or 4,300 degrees Celsius, according to NASA’s Jet Propulsion Laboratory at the California Institute of Technology.
KELT-9b is a gas giant, much like Jupiter, but it is much larger and much hotter. It is about twice the size of Jupiter and orbits its host star every 1.48 days. The planet is so close to its star that it is tidally locked, meaning one side of the planet is always facing the star. This means that one side of the planet is much hotter than the other.
KELT-9b is so hot that it is actually in danger of evaporating. Its atmosphere is being stripped away by the intense radiation from its host star. This process is known as “evaporation” and it is happening at an alarming rate. In fact, it is estimated that the planet will completely evaporate in just 30 million years.
KELT-9b is the hottest known planet in the universe, but it is not the only one. There are other exoplanets that have been discovered that are even hotter. These include WASP-12b, which has a surface temperature of 8,000 degrees Fahrenheit, and WASP-19b, which has a surface temperature of 8,400 degrees Fahrenheit.
The reason why these planets are so hot is because they are so close to their host stars. They are so close that they are tidally locked, meaning one side of the planet is always facing the star. This means that one side of the planet is much hotter than the other.
So, while Venus may be the hottest planet in our Solar System, it is not the hottest planet in the universe. That honor belongs to KELT-9b, a distant exoplanet located 670 light-years away from Earth. It has a surface temperature of 7,800 degrees Fahrenheit, or 4,300 degrees Celsius, and is in danger of evaporating due to the intense radiation from its host star. Other exoplanets, such as WASP-12b and WASP-19b, are even hotter than KELT-9b. So, if you’re looking for a planet that’s hotter than Venus, look no further than these distant exoplanets.
