description Overview

Kepler-7b

Kepler-7b is a transiting hot Jupiter discovered during NASA's Kepler mission. It has a large radius relative to its mass, giving it an unusually low average density, and it orbits very close to its host star. Measurements of changes in reflected starlight across its orbit revealed an unevenly bright dayside, interpreted as evidence for patchy, reflective clouds concentrated toward one side of the...

HD 209458 b

HD 209458 b is a giant exoplanet orbiting a Sun-like star approximately 153 light-years away. It gained significant attention as the first planet detected through the transit method in 1999. Scientists identified an escaping hydrogen atmosphere, marking the initial confirmation of such atmospheric loss in a transiting exoplanet. This discovery provides valuable data for understanding planetary evo...
