WASP-93 b
WASP-93 b Encyclopedic Information
WASP-93 b is a celestial heavyweight that pushes the boundaries of our understanding of planetary formation. Located roughly 3,900 light-years away in the constellation Cassiopeia, this hot Jupiter is a gargantuan gas giant that orbits its host star so closely that a single year on this world passes in just over two and a half Earth days. Its existence serves as a stark reminder of the wild diversity of exoplanetary systems, challenging models that suggest gas giants should only form in the cooler, outer reaches of stellar systems.
Beyond its sheer scale, WASP-93 b is a laboratory for extreme physics. By orbiting its parent star at such a breakneck pace, the planet is subjected to intense stellar radiation, leading to an atmosphere that is likely puffed up and blistering. For astronomers, studying this world is akin to looking into the chaotic, high-energy furnace of planetary evolution, providing crucial data on how massive planets survive—or succumb to—the gravitational tug-of-war with their parent stars.

History & Significance
The discovery of WASP-93 b was announced in 2015 as part of the Wide Angle Search for Planets (WASP) project, a prolific international consortium that has revolutionized our catalog of alien worlds. Utilizing the transit method—where the planet is detected by the subtle dimming of its host star as it passes in front—astronomers were able to confirm its existence through ground-based robotic telescopes. While WASP-93 b lacks the ancient mythological baggage of the planets within our own solar system, its name carries the legacy of modern astronomical exploration, representing the 93rd success story of a survey that has fundamentally changed our perspective on the galaxy.
Since its identification, WASP-93 b has become a target of interest for follow-up studies utilizing high-resolution spectrographs. Unlike the mythological giants of antiquity, this world is a product of data-driven discovery, yet it holds a different kind of allure: the frontier spirit. It belongs to a generation of exoplanets that have transitioned astronomy from the era of Do other planets exist? to the current age of What are these planets actually made of? Every observation of WASP-93 b adds another piece to the puzzle of how planetary systems emerge from the primordial dust of the cosmos.
Physical Structure
Physically, WASP-93 b is a colossal sphere of hydrogen and helium, boasting a mass roughly 4.6 times that of Jupiter. Because it orbits so close to its F-type host star, the planet’s atmosphere is likely subjected to extreme thermal expansion. This bloating effect is a hallmark of many hot Jupiters, where the intense heat from the star causes the gaseous layers to swell, creating a low-density profile that is significantly less compact than the gas giants in our own neighborhood. The atmosphere is likely a swirling, chaotic environment of high-altitude clouds and metal-rich vapors, driven by the planets intense internal heat and tidal locking.
Beneath its thick, turbulent outer envelope, scientists theorize a dense, rocky, or metallic core, the result of the planet’s heavy-element accumulation during its infancy. Because it is tidally locked—meaning one side always faces the star—WASP-93 b likely experiences extreme temperature gradients between its scorching dayside and its relatively cooler nightside. This massive thermal imbalance could drive supersonic winds that whip around the globe, redistributing heat in a perpetual, high-velocity atmospheric race. It is a world of extremes, where the boundary between atmosphere and interior blurs in a high-pressure, high-temperature dance that defines the life cycle of a gas giant.
