Abstract :
With over 5000 confirmed exoplanets, astronomers need a more simple and efficient way to evaluate the habitability of each planet. The goal of this research project is using data from the NASA Exoplanet Archive and the ESI index (earth similarity index) to rank rock samples- a sample of terrestrial (rocky) prefiltered to be located within their star's habitable zone- planets based on two main criteria : planetary size and distance from their host star . Our results successfully rank some high probability worlds and identify top tier candidates such as Kepler 1649c and Ross 128 b at the apex of similarity to earth. To minimize assumptions and to account for the majority of planetary surfaces, this project isolates interior ESI, evaluating candidates strictly on physical parameters: planetary size, bulk, and density. Ultimately this provides a baseline for future atmospheric characterization.
