Awasis,[2] originally named HD 136418 b, is an extrasolar planet orbiting the G-type star Nikawiy (HD 136418) approximately 320 light years away in the constellation Boötes[1] It has a notable orbit, staying within the known habitable zone.[citation needed] It also has a star very similar in temperature as the Sun.[3]
The planet was originally given the temporary designation "HD 136418 b", as the second object in the HD 136418 system, before being officially named "Awasis" by representatives of Canada in the 2019 NameExoWorlds contest held by the IAU, named after the Cree word for "child". In the same competition, Awasis's parent star HD 136418 was named Nikawiy after the Cree word for "mother".[2]
