 The databases are frequently updated with new data from peer-reviewed publications and conferences.In their respective pages, the planets are listed along with their basic properties, including the year of planet's discovery, mass, radius, orbital period, semi-major axis, eccentricity, inclination, longitude of periastron, time of periastron, maximum time variation, and time of transit, including all error range values.The individual planet data pages also contain the data on the parent star, including name, distance in parsecs, spectral type, effective temperature, apparent magnitude, mass, radius, age, and celestial coordinates (Right Ascension and Declination).
