WASP-99 b
WASP-99 b Encyclopedic Information
WASP-99 b is a cosmic heavyweight that defies our cozy terrestrial expectations. Classified as a hot Jupiter, this gas giant orbits its host star with such intensity that it completes a full year in just under three Earth days. Located roughly 1,400 light-years away in the constellation Cetus, it represents the extreme end of planetary evolution. Studying worlds like WASP-99 b is vital for astronomers because it pushes our understanding of how massive planets can survive, and even thrive, in the scorching proximity of their stellar parents, offering a window into the chaotic diversity of our galaxy.

History & Significance
The discovery of WASP-99 b was a triumph of the Wide Angle Search for Planets (WASP) project, a collaborative international effort that revolutionized exoplanetary science through ground-based transit photometry. First identified and confirmed in 2013, the planet was unveiled as part of a wave of discoveries that proved hot Jupiters were far more common than early models suggested. Unlike the planets of our solar system, which carry names rooted in ancient Greco-Roman pantheons, WASP-99 b bears the utilitarian designation of its survey mission, acting as a testament to the modern era of automated, data-driven celestial cartography.
Physical Structure
Physically, WASP-99 b is a bloated behemoth, possessing a mass approximately 2.7 times that of Jupiter. Because of its extreme proximity to its host star, the planet’s atmosphere is likely a roiling furnace where temperatures soar to extreme levels, effectively puffing the planet up to a larger radius than it would otherwise have. It is primarily composed of hydrogen and helium, swirling in a dense, opaque shroud of clouds that likely contain exotic metallic vapors. The intense radiation from its star creates a high-energy environment, potentially driving fierce, supersonic winds that redistribute heat across its day and night sides in a permanent, turbulent dance.
