Hi there! I'm Dr. Stella, an astrophysicist with a particular fascination with exoplanets and stellar evolution. I've dedicated years to studying these celestial bodies, their formation, and the extreme conditions that govern their existence.
The question of the hottest planet in the universe is truly intriguing! While we haven't explored the entire universe to pinpoint the absolute hottest, I can shed light on the factors that contribute to a planet's scorching temperatures and discuss some of the hottest known planets.
Firstly, it's important to understand that a planet's temperature is primarily determined by its proximity to its host star. The closer a planet orbits its star, the more intense the stellar radiation it receives, leading to significantly higher temperatures. We're talking about temperatures that can vaporize metals!
Another crucial factor is the type of star the planet orbits. Hot, massive stars emit far greater energy than our Sun, a relatively cool and stable star. Planets orbiting these stellar behemoths experience intense heat even at distances considered far in our solar system.
Now, let's dive into some examples. Within our own solar system, **<font color='red'>Venus</font>** holds the title of the hottest planet. You might be surprised, given that <font color='red'>Mercury</font> is closer to the Sun. However, Venus possesses a dense atmosphere composed primarily of carbon dioxide, which traps heat through a runaway greenhouse effect. This results in a scorching surface temperature averaging around 867°F (464°C), hot enough to melt lead!
Venturing beyond our solar system, we encounter even more extreme temperatures. Exoplanets like **<font color='red'>KELT-9b</font>** truly redefine the meaning of hot. This gas giant, about three times the mass of Jupiter, orbits extremely close to its star, KELT-9, a blue supergiant significantly hotter and more massive than our Sun. The intense stellar radiation heats KELT-9b's atmosphere to a mind-boggling 7,800°F (4,300°C), hotter than the surface of some stars!
Another scorching contender is **<font color='red'>WASP-12b</font>**, a gas giant tidally locked to its star, meaning one side permanently faces the stellar inferno. The dayside temperature of WASP-12b is estimated to be a staggering 4,700°F (2,600°C), making it one of the hottest exoplanets discovered so far.
It's important to remember that our understanding of exoplanets is constantly evolving as we discover new worlds and refine our observational techniques. While the planets I've mentioned are among the hottest known, the vastness of the universe suggests even more extreme environments likely exist, waiting to be discovered. The quest to find the hottest planet is an ongoing journey of scientific exploration!

Mercury is the planet that is closest to the sun and therefore gets more direct heat, but even it isn't the hottest. Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system.
