description Overview

TrES-2b

TrES-2b is a giant exoplanet orbiting the star GSC 03549-02807. It’s notable as the darkest known exoplanet, reflecting extremely little light – less than one percent. This makes it a valuable subject for studying planetary atmospheres and extreme conditions. Astronomers and researchers interested in characterizing hot Jupiters and understanding dark object properties study TrES-2b.

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...
