WebNov 18, 2015 · A good way to estimate how habitable a planet is the Earth Similarity Index (ESI). This number is calculated from the exoplanet’s radius, density, surface temperature and escape velocity, which... The Earth Similarity Index (ESI) is a proposed characterization of how similar a planetary-mass object or natural satellite is to Earth. It was designed to be a scale from zero to one, with Earth having a value of one; this is meant to simplify planet comparisons from large databases. The scale has no quantitative … See more The ESI, as proposed in 2011 by Schulze-Makuch et al. in the journal Astrobiology, incorporates a planet's radius, density, escape velocity, and surface temperature into the index. Thus the authors describe the index as having … See more The classification of exoplanets is difficult in that many methods of exoplanet detection leave several features unknown. For example, with the transit method, measurement of … See more • List of natural satellites See more Although the ESI does not characterize habitability, given the point of reference is the Earth, some of its functions match those used by habitability measures. As with the definition of the habitable zone, the ESI uses surface temperature as a primary function … See more The index can be calculated for objects other than planets, including natural satellites, dwarf planets and asteroids. The lower average … See more • HEC: Data of Potential Habitable Exoplanets and Exomoons See more
