Nov. 20, 2018 AAVSO to archive amateur astronomer exoplanet data: more here

Oct. 29, 2018 A new tool is now accessible on the database. This tool can be used to easily simulate the climate on terrestrial planets. It is accessible here.

Oct. 25, 2018 All of our database is accessible in python via our API. We have added a tutorial to use the API to query our database and collect/handle the data you want in an easy way.

July 24, 2018 We have created a new interactive plot that gives a new way of looking at the population of exoplanets that we know of in the nearby solar neighbourhood. On this plot the Sun is at the centre and the various planets can be seen at their respective distances from our Sun. This gives quite an interesting perspective.

July 7, 2018 There is a new section dedicated to planets in stellar binary systems. A plot is computed from the database to show the planets' locations compared to the stellar companions and the theoretical stability limit to form planets around binaries for all systems with binaries at <200au.
