Hello, I'm Dr. Stellar, an astrophysicist specializing in exoplanet research. It's a fascinating question you've posed about the hottest planet in the universe.
To accurately address this, we need to define what we mean by "hottest." Are we talking about surface temperature, internal temperature, or perhaps the temperature of a planet's atmosphere? Each of these factors can contribute to a planet's overall heat.
Let's break down these different temperature measurements and what makes a planet hot:
Surface Temperature:
This is the most straightforward measurement and refers to the temperature at a planet's surface. Planets with a strong stellar insolation, meaning they receive a large amount of radiation from their host star, tend to have higher surface temperatures.
However, surface temperature can also be affected by a planet's atmosphere. Planets with dense atmospheres rich in greenhouse gases, like carbon dioxide, can experience a runaway greenhouse effect, trapping heat and leading to extremely high surface temperatures.
Internal Temperature:
The internal temperature of a planet reflects the heat generated within its core. This heat can be a result of radioactive decay or tidal forces caused by a planet's proximity to its host star.
Atmospheric Temperature:
A planet's atmosphere can be heated by various processes, including stellar insolation, convection, and the absorption of radiation emitted from the planet's surface. Some planets have atmospheres with extreme temperatures due to the presence of specific molecules, such as hydrogen cyanide, which absorb and trap heat.
Identifying the Hottest Planet:
While we can measure the surface temperature of planets within our solar system, the challenge arises when determining the hottest planet in the entire universe. This is because we have only discovered a fraction of the exoplanets out there, and our technology is limited in our ability to accurately measure the temperatures of distant planets.
**Current Contenders for the Hottest Planet:**
As of now, the hottest planet known is KELT-9b, a gas giant orbiting the star KELT-9. With a surface temperature exceeding 4,600 degrees Celsius (8,300 degrees Fahrenheit), KELT-9b is hotter than many stars.
**However, there are several factors that make it difficult to definitively claim KELT-9b as the hottest planet:**
* Limited Data: We have limited observational data on exoplanets, making it challenging to compare and verify temperatures across different systems.
* Variability: The temperature of a planet can vary depending on its orbital position relative to its host star. We might only be observing a planet at a specific point in its orbit.
* Unidentified Factors: There may be other factors influencing a planet's temperature that we haven't yet discovered or accounted for.
The Future of Hot Planet Discovery:
As our observational techniques improve, we are likely to discover even hotter planets in the vast expanse of the universe. The field of exoplanet research is continuously evolving, and new discoveries are being made all the time.
**Therefore, while KELT-9b currently holds the title of hottest known planet, this title is likely to be challenged as we uncover more information about exoplanets.**
This exciting field of study will continue to push our understanding of planetary formation and the diversity of worlds that exist beyond our solar system.

The Hottest Planet in The Known Universe Has Been Found - And It's Warmer Than Most Stars. Scientists have found one of the craziest exoplanets yet. ... For comparison, the surface of our Sun is around 5,800 Kelvin, and even its closest planet Mercury only reaches a measly 700 Kelvin on the surface.
