Corro 7b experiences rock rain due to extreme temperatures caused by its proximity to a star. Different exoplanets like J1407b, Pso J318.5-22, Wasp 12b, and Captain B offer unique characteristics, challenging existing assumptions about exoplanet compositions and potentially leading to discoveries of extraterrestrial life forms.
Insights
- Corro 7b, an exoplanet 489 light years away, experiences rock rain due to extreme heat vaporizing rocks, a result of its proximity to the star.
- Captain B, an ancient planet orbiting a red sub-dwarf star, offers insights into the early universe despite being potentially habitable, with an Earth Similarity Index of 0.67.

Exoplanet Discoveries: Extreme Conditions and Surprising Realities
- Corro 7b is an exoplanet where it rains rocks the size of Earth, located 489 light years away, with temperatures reaching 4,700 degrees Fahrenheit.
- The planet's proximity to its star causes extreme heat, leading to vaporized rock that condenses into fine gravel, creating a literal rock rain.
- The planet's past as a gas giant that moved closer to its star, resulting in its rocky core, is a terrifying reality of Corro 7b's existence.
- J1407b, a massive gas giant with 30 rings 200 times wider than Saturn's, possibly formed due to the destruction of its satellites, leading to its unique ring system.
- The rings of J1407b, with a mass of 7.34 x 10^21 tons, have gaps indicating past collisions, allowing scientists to study the planet using the transit observation method.
- Pso J318.5-22 is a rogue planet, eight times larger than Jupiter, drifting through space without orbiting a star, allowing astronomers to study its layers of clouds and extreme weather conditions.
- Wasp 12b, a gas giant shaped like an egg, is being torn apart by its host star, with temperatures reaching 4,100 degrees Fahrenheit, potentially forming a gas and dust cloud.
- The discovery of water streams and the possibility of a diamond surface on Wasp 12b challenge previous assumptions about the planet's composition.
- Formal Hot B, previously known as Dagon, was initially thought to be a massive exoplanet but was later theorized to be a dissipating dust cloud from a rare collision event.
- Captain B, an ancient planet 11.5 billion years old, orbits a red sub-dwarf star, potentially within the habitable zone despite its close proximity, offering insights into the early universe.

Potential for Extraterrestrial Life on Planet B
- The ESI (Earth Similarity Index) for planet B is 0.67, making it similar to planets KOI4, KOI4005-01, and Kepler-62f, potential candidates for discovering extraterrestrial life forms. The age of a planet significantly increases the chances of it being habitable, with 11.5 billion years on planet B potentially allowing for the development of microorganisms.
