description Overview

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...
