WebJan 22, 2024 · The Earth Similarity Index (ESI) is defined to find the similarity with Earth, which ranges from 1 (Earth) to 0 (totally dissimilar to Earth). ESI can be computed using four physical parameters of a planet, namely radius, density, escape velocity and surface temperature. The surface temperature entering surface ESI is a non-observable quantity ... Webmodule EarthSimilarityIndex type Planet = { mass : float; radius : float; density : float; g : float; ve : float; a : float; Tsurf : float; Teq : float } let earth = { mass = 1.0; radius = 1.0; …

Comparative linguistics - a quantitative method

WebThe Earth Similar Index (ESI) is a proposed characterization to detail how similar a planet or natural satellite is to the planet Earth. The index has a scale of "0.00" to "1.00", with … 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 radius can be highly accurate, but mass and density are often estimated. Likewise … 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.
