These are artistic representations of the only known planets around other stars (exoplanets) with any possibility to support life as we know it. Earth, Mars Jupiter, and Uranus are shown for scale in the right side. All are ranked with the Earth Similarity Index (ESI), a measure of Earth-likeness from zero to one, with a value of one being identical to Earth.

Exoplanet Orbit Database | Exoplanet Data Explorer The Exoplanet Data Explorer is an interactive table and plotter for exploring and displaying data from the Exoplanet Orbit Database. The Exoplanet Orbit Database is a carefully constructed compilation of quality, spectroscopic orbital parameters of exoplanets orbiting normal stars from the peer-reviewed literature, and updates the Catalog of nearby exoplanets. A detailed description of the Exoplanet Orbit Database and Explorers is published here and is available on astro-ph. In addition to the Exoplanet Data Explorer, we have also provided the entire Exoplanet Orbit Database in CSV format for a quick and convenient download here.
