Flexi Says: According to the discovery of a Harvard researcher, Kaitlyn Loftus, there is a similarity between the size of the raindrops falling on other exoplanets and that on earth. As per the study, computer models were used to investigate the shape of the raindrop, its falling, and evaporation speed. ith the study, it was determined that the size of the raindrop remains relatively constant across different planetary environments.
