WASP-87 b
WASP-87 b Encyclopedic Information
WASP-87 b is a quintessential Hot Jupiter, a gargantuan world that defies our solar systems conventional boundaries. Orbiting its host star at a blistering proximity, this gas giant represents the extreme diversity of planetary formation in our galaxy. It serves as a celestial laboratory for astronomers, helping us understand how gas giants can migrate inward to become scorched, fast-orbiting behemoths that challenge traditional theories of planetary evolution.

History & Significance
Discovered in 2014 by the Wide Angle Search for Planets (WASP) consortium, WASP-87 b was identified using the transit method—a technique where astronomers detect a slight dip in starlight as the planet crosses the face of its sun. While it lacks a mythological namesake, its discovery marked a significant milestone for the South African Astronomical Observatory, which provided critical ground-based follow-up observations to confirm the existence of this sweltering world. Unlike the planets of our inner solar system, which were known to ancient civilizations, WASP-87 b remained a hidden giant until the modern era of high-precision photometry brought it into focus.
Since its cataloging, the planet has become a subject of intense study for researchers utilizing both ground-based telescopes and space-borne instruments. It stands as a testament to the success of the WASP project, which has successfully cataloged dozens of exoplanets by scanning vast swaths of the sky. By analyzing the light spectrum during its transit, scientists have been able to peel back the layers of this mysterious world, piece by piece, turning a mere flicker of light into a complex, tangible planetary destination.
Physical Structure
WASP-87 b is a bloated, low-density gas giant that likely resembles a puffy, atmospheric furnace. Because it orbits so close to its parent star, the planet is subjected to intense tidal forces and extreme stellar radiation, causing its upper atmosphere to swell significantly. It is primarily composed of hydrogen and helium, much like Jupiter, but the similarities end there; here, the temperatures are hot enough to vaporize metals and create clouds of exotic minerals, such as silicates or iron, which swirl through the turbulent, superheated skies.
Deep beneath its swirling, cloud-shrouded exterior, the planet likely hosts a core of heavy elements, potentially compressed into a dense, metallic state under the weight of its immense gaseous envelope. The planet is almost certainly tidally locked, meaning one side faces a perpetual, scorching noon while the other remains trapped in an eternal, albeit still warm, night. This stark temperature gradient creates powerful, planet-wide winds that redistribute heat, effectively turning the entire globe into a dynamic, shifting weather machine that defies any earthly comparison.
