HAT-P-36, also referred to as Tuiren[4] is a 12th magnitude G-type main-sequence star estimated to be approximately 958 light-years away from Earth[2] in the constellation Canes Venatici. HAT-P-36 is too faint to be seen with the naked eye, but it is possible to view it with binoculars or a small telescope. In 2012 a hot Jupiter-type exoplanet was discovered orbiting HAT-P-36 with an orbital period of about 1.3 Earth days.[5] In December 2019, HAT-P-36 was named Tuiren and its planetary companion, HAT-P-36b, was named Bran as a result of Ireland's contribution to the 2019 NameExoWorlds campaign.[6] Bran has a mass approximately 1.8 times that of Jupiter and a radius 1.2 times larger.
