The weather on KELT-18 b, an exoplanet located in the constellation CISCA, is quite extreme and unpredictable due to its close proximity to its host star. Today, July 31st, the weather on KELT-18 b is especially tumultuous. The planet experiences a rapid shift from intense heat to cold temperatures within a short timeframe.

The day begins with a scorching temperature of 42 degrees Celsius at noon, creating a hostile environment for any potential life forms. However, as the afternoon progresses, a cool front moves in, bringing temperatures down to a more bearable 18 degrees Celsius by evening. The planet’s thick atmosphere plays a crucial role in retaining heat during the day and then releasing it gradually during the cooler hours.

Did you know that KELT-18 b is one of the few exoplanets known to have an atmosphere primarily composed of carbon dioxide, similar to Earth’s? This unique composition contributes to its dynamic weather patterns and provides insights into the potential habitability of this fascinating distant world!
