Wasp 12b is similar in size to Jupiter but has significant differences due to its extreme environment. 

This exoplanet is located approximately 1,400 light-years away in the constellation Auriga. It was discovered using the transit method, which observes the dimming of a star as a planet passes in front of it. 

Wasp 12b is also classified as a gas giant, and its internal structure is expected to share similarities with that of other hot Jupiters. It likely has a solid or liquid core surrounded by a thick atmosphere of hydrogen and helium, with varying amounts of heavier elements. The intense gravitational forces exerted by its host star result in significant tidal heating, which may affect the planet's internal dynamics and structure, potentially leading to a more diffuse atmosphere and influencing the distribution of materials within the planet. 

The intense tidal forces exerted by its host star cause Wasp 12b to be elongated, giving it an egg-like shape rather than a perfect sphere. Its extreme conditions provide a unique laboratory for studying the effects of stellar interactions on gas giants. 

Discovery Method: Transit Method

Year Discovered: 2008

Details: Wasp 12b was discovered using the Wide Angle Search for Planets (WASP) project, which employs the transit method. The project monitored the brightness of thousands of stars, identifying Wasp 12b when it caused a measurable dimming during its transit.
