Kelt-9B

A constant rain of molten titanium the size of cities cascades the vast seas of this exoplanet.

Size and Mass: KELT-9b is roughly 1.8 times the size of Jupiter and 2.9 times its mass. 

Tidal Locking: Due to its close proximity to its star, KELT-9b is tidally locked, meaning the same side always faces the star. 

Extreme Heat: The planet's dayside temperature can reach over 7,800 degrees Fahrenheit (4,600 Kelvin), which is hotter than many stars. 

Atmospheric Effects: The intense heat causes the planet's atmosphere to expand and even potentially vaporize, leading to a superheated, metallic atmosphere.
