Time to Name a Planet

In celebration of 100 years of the International Astronomical Union, the IAU NameExoWorld  global competition allows any country in the world to give a popular name to a selected exoplanet and its host star. New Zealand has been assigned the planet HD 137388b and its host star HD 137388 and we need your help in choosing names!  You can make a submission here between 1 September 2019 and 30 September 2019 (5:00 p.m. NZST). A panel of judges will select the name of the star and the planet by 30 October 2019 and will make its submission to the IAU by the 31 October 2019. IAU will make it’s final announcement in by 31 December 2019 . The winner will then be notified via email. Please note that entries can only be accepted from people living in NZ during the time of the submission.
