Today, as more exoplanets are discovered, the desire for finding habitable ones increases. There are many climate models for assessing the habitability and climate changes of exoplanets. One of the simplest, yet accurate enough models is the latitudinal energy balance model. It is a diffusion-like process, which simulates the temperature profile over the planet surface. In this study, our purpose is to investigate the impact of some parameters of exoplanets on their temperature and habitability. Our exoplanet candidates are GJ 273b, Trappist-1d, 'Tau Ceti-e, GJ 3323b, and the studied parameters are planet eccentricity, diurnal period, obliquity and its fraction of ocean. In each case, the selected parameter was varied in a wide range. Finally, the probable descriptions of results are presented.
