WASP-121 b

WASP-121b is a fascinating exoplanet known for its extreme conditions. It's a "hot Jupiter," meaning it's a gas giant that orbits very close to its star.  

Here are some key features of WASP-121b:

• Extreme Heat: Due to its proximity to its star, WASP-121b is incredibly hot, with surface temperatures exceeding 2,500 degrees Celsius.  

• Tidal Forces: The intense gravitational forces from its star are causing WASP-121b to be stretched and deformed, leading to a unique shape.  

• Rapid Orbital Period: It orbits its star in just 1.27 days, making it one of the fastest-orbiting planets known.  

• Mass Loss: The extreme heat and tidal forces are causing WASP-121b to lose mass at a rapid rate.

• Water Vapor in Atmosphere: WASP-121b is the first exoplanet found to contain water in its stratosphere.  

WASP-121b is a valuable object for studying the extreme conditions that can exist in exoplanetary systems. It provides insights into the physical processes that shape these exotic worlds.
