WASP-105 b
WASP-105 b Encyclopedic Information
WASP-105 b is a celestial heavyweight, a gas giant that defies the cozy expectations of our own solar system. Located roughly 500 light-years away in the constellation Volans, this Hot Jupiter orbits its host star with a swiftness that would make a planetary scientist’s head spin. By studying these bloated, gaseous worlds, astronomers are effectively building a cosmic map of how solar systems evolve, teaching us that the universe is far more creative—and chaotic—than the neatly ordered planets we call home. It stands as a testament to the diversity of planetary formation, proving that giant worlds can exist in extreme proximity to their suns, challenging our traditional models of orbital migration.

History & Significance
The discovery of WASP-105 b was a triumph of the Wide Angle Search for Planets (WASP) project, a survey that has revolutionized our understanding of the exoplanetary census. First identified in 2017, the planet was revealed through the transit method, where scientists meticulously watched for the telltale dip in starlight as the giant world passed in front of its host, WASP-105. While it lacks a mythological namesake from antiquity, its designation within the WASP consortium ties it to a modern-day era of automated, high-precision discovery that has democratized the search for distant worlds. Unlike the planets of our solar system, which were named by ancient observers looking up at the night sky with wonder, WASP-105 b is a child of the digital age, born from complex light curves and sophisticated computer algorithms.
Since its confirmation, WASP-105 b has become a focal point for follow-up studies aiming to characterize the atmospheres of gas giants. Its discovery contributes to a broader scientific narrative: the transition from merely finding planets to understanding what they are actually made of. While it hasnt been the primary target of a dedicated flagship mission like the James Webb Space Telescope yet, it remains a high-priority candidate for atmospheric spectroscopy, serving as a vital data point for researchers trying to unlock the secrets of planetary atmospheres across the galaxy.
Physical Structure
WASP-105 b is a behemoth, boasting a mass roughly 1.8 times that of Jupiter, yet it is significantly less dense than one might expect for such a massive object. This puffy nature is a hallmark of many Hot Jupiters; the intense radiation from its host star heats the upper layers of its atmosphere, causing the gases to expand and inflate like a celestial balloon. Composed primarily of hydrogen and helium, the planet likely features a swirling, cloud-covered exterior where extreme temperatures prevent any solid surface from forming. Deep within its interior, the immense pressure likely compresses these gases into exotic states of matter, potentially creating a core of heavy elements hidden beneath thousands of miles of turbulent, superheated clouds.
The atmosphere of WASP-105 b is a theater of extreme weather. We suspect that high-altitude winds circulate heat from the day-side to the night-side, creating a global climate of perpetual storminess. Given its proximity to its star, the planet is almost certainly tidally locked, meaning one side faces its sun in an eternal, scorching day, while the other remains in a frozen, dark night. This drastic temperature gradient likely fuels jet streams that tear through the atmosphere at supersonic speeds, painting the planet’s upper clouds in hues of muted gold and deep indigo, though these colors remain hidden from even our most powerful telescopes for now.
