Ultra-hot Jupiter known as WASP-76 b hotter than previously thought

WASP 76B is a gas giant exoplanet with an orbit of less than 10 days, possibly hotter than previously thought. It completes an orbit every 1.8 Earth days and is tidally locked, with extreme temperatures on its day and night sides. The planet is 1.85 times wider than Jupiter but has only 85% of its mass. The day side is hot enough to vaporize iron, which condenses and falls as molten iron rain on the night side. A new study reveals ionized calcium in its upper atmosphere, suggesting strong winds or higher atmospheric temperatures.
