HAT-P-23 b
HAT-P-23 b Encyclopedic Information
Imagine a world so close to its parent star that a single year passes in just over 48 hours. Welcome to HAT-P-23 b, a scorching Hot Jupiter that defies the comfortable norms of our own solar system. Located roughly 1,200 light-years away in the constellation Delphinus, this gas giant is a celestial furnace, offering astronomers a front-row seat to the extreme dynamics of planetary evolution. It serves as a stark reminder of the wild diversity found in our galaxy, where massive worlds dance on the razors edge of their own stellar incineration.

History & Significance
The discovery of HAT-P-23 b was a triumph of the HATNet Project (Hungarian-made Automated Telescope Network), a global network of small, automated telescopes designed to hunt for transiting exoplanets. In 2010, researchers identified the telltale dip in starlight as the planet passed in front of its host star, HAT-P-23. While the planet lacks a mythological namesake from ancient pantheons, its scientific designation is a testament to the modern era of ground-based surveys that have revolutionized our understanding of the cosmos by proving that giant planets are far more common in close-orbit configurations than previously imagined.
Physical Structure
HAT-P-23 b is a bloated behemoth, possessing roughly twice the mass of Jupiter but packed into a radius that makes it significantly denser than its solar system counterpart. Because it orbits its star at a distance nearly 20 times closer than Mercury orbits the Sun, the planet is perpetually scorched by intense stellar radiation. This extreme heat causes the upper atmosphere to swell, creating a puffy, low-density exterior that likely experiences hurricane-force winds and potentially even the evaporation of its own gaseous layers into space.
