Our first glimpse at planets outside of the solar system we call home came in 1992 when several terrestrial-mass planets were detected orbiting the pulsar PSR B1257+12. In this dataset, you can become a space explorer too by analyzing the characteristics of all discovered exoplanets (plus some familiar faces like Mars, Saturn, and even Earth). Data fields include **planet** and **host star attributes**, **discovery methods**, and (of course) **date of discovery**. Data was originally collected and continues to be updated by [Hanno Rein][1] at the [Open Exoplanet Catalogue Github repository][2]. If you discover any new exoplanets, please submit a pull request there. ## Constants - **Jupiter mass**: 1.8991766e+27 kg - **Solar mass**: 1.9891e+30 kg - **Jupiter radius**: 69911000 m - **Solar radius**: 6.96e+08 m ## License The database is licensed under an MIT license.
