Click image for more details, or click here for larger version. These are artistic representations of all the planets around other stars (exoplanets) with any potential to support surface life as we know it. All of them are larger than Earth and we are less certain about their composition and habitability, but they represent the best objects of interest for future observations. They are ranked from best to worst with the Earth Similarity Index (ESI), a measure of Earth-likeness, but none yet seems to be a true Earth-like planet. This selection of worlds is also subject to change as new interpretations or astronomical observations are made. Earth, Mars, Jupiter, and Uranus are shown for scale on the right.

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.
