Americans, we can name an exoplanet!


The International Astronomical Union (IAU) invites you to help name an exoplanet and its star.

A national committee for the US naming event has been specially created by the National Outreach Coordinators to carry out the campaign at the national level. The national committee strictly follows the methodology and guidelines set up by the IAU100 NameExoWorlds Steering Committee and is responsible for providing the conditions for public participation, disseminating the project in the country and establishing a voting system.

The US Exoplanet Naming Campaign collected names from September 15 – October 15, 2019. The US National Committee received hundreds of proposals. A group of 40 amateur and professional astronomers, teachers and students will identify 10 proposals that will be voted on by the US public. This list of 10 semi-finalists will be made public and available for public voting on November 1st, 2019. Public voting will be open until November 14, 2019. The top three selected by US voters will be submitted by November 15 to the IAU100 NameExoworlds Steering Committee for the final choice. The final result will be announced by the IAU the week of December 16 – 21, 2019.
