This study is part of a newly growing science in exoplanet characteristics. We present an initial attempt to investigate the relationship between the eclipse depth of giant exoplanets and the metallicity of their host stars to show the best eclipse depth-metallicity trend. This will help us to better understand the conditions that lead to giant planets formation, which helps to postulate about the formation of our Solar System and more generally the planet formation theories. Previous studies have shown that stars with giant planets tend to have higher metallicities than stars without giant ...
