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...

WASP-121b

WASP-121b is an exoplanet classified as a giant, resembling a hot Jupiter. Its notable characteristic is its extremely short orbital period of approximately 1.27 days around its host star. This rapid transit and intense heat—with dayside temperatures exceeding 2400 K—have allowed scientists to detect its stratosphere. The planet’s study is valuable for understanding atmospheric evolution around cl...
