WASP-72 b
WASP-72 b Encyclopedic Information
WASP-72 b is a celestial powerhouse that pushes the boundaries of our understanding of planetary evolution. Located roughly 3,300 light-years away in the constellation Fornax, this Hot Jupiter is a gas giant that defies the cozy norms of our own solar system. Orbiting its host star at a blistering pace, it represents a class of worlds that are essentially frying in the intense radiation of their suns, offering astronomers a high-stakes laboratory to study atmospheric stripping and extreme thermal dynamics. Its existence challenges us to rethink how massive planets migrate inward, turning the quiet void of space into a theater of cosmic chaos.

History & Significance
The discovery of WASP-72 b was a triumph for the Wide Angle Search for Planets (WASP) consortium, a ground-based project utilizing robotic telescopes to detect the subtle dimming of stars caused by transiting exoplanets. Identified in 2013, this world was plucked from the darkness through the transit method, where scientists meticulously tracked the light curves of its host star, WASP-72. Unlike the planets of our solar system, which are named after ancient pantheons, WASP-72 b carries the utilitarian but prestigious stamp of modern survey science, marking it as a significant milestone in the ongoing quest to catalog the diverse menagerie of our galaxy.
Physical Structure
WASP-72 b is a gargantuan sphere of gas, boasting a mass roughly 1.5 times that of Jupiter and a radius that suggests a puffy, bloated atmosphere. Because it hugs its host star so tightly—completing a full orbit in just over two Earth days—the planet is subjected to extreme tidal forces and scorching temperatures that likely exceed 2,000 degrees Celsius. This intense heat causes the planet’s upper atmosphere to expand, creating a hazy, metallic-rich shroud that may be actively evaporating into space, leaving behind a glowing trail of ionized particles as it screams through its orbital path.
