This IAU100 project gives every country in the world the opportunity to name an exoplanet and its host star. Ireland has been assigned the honour of giving a popular name to HAT-P-36b, an exoplanet 1.8 times Jupiter’s mass, and its host star which can been found in the Canes Venatici constellation. The planet’s host star is comparable in age and mass to our Sun.

The planet was discovered by the HATnet collaboration in 2012 and orbits its parent star every 1.3 days.

The NameExoWorlds campaign has selected planetary systems for naming composed of planets orbiting stars that could be observed with a small telescope from the latitude of the capital of each country. The system often has a link with the assigned country, such as the facilities used to discover the planet, or the scientists involved in the discovery of the planet. ​The existence of the planet is generally more secure for systems which were discovered earlier, as they have had more years of research to survive further scrutiny. For this reason, the sample is focused on exoplanets revealed during the first two decades of exoplanet exploration, with most discovery dates before 2012. The visual brightnesses range between 6th and 12th magnitude. The planets were all discovered via either the Doppler spectroscopy (radial velocity) method or transit method, and all were discovered using ground-based telescopes. The planets are all likely to be gas giants similar to Jupiter and Saturn, with estimated masses between 10% and 500% that of Jupiter. All these systems are composed of single stars with only one known planet orbiting around them. It is possible that the stars have additional planetary and stellar companions which may be discovered in the future. This is so that each country has an equal opportunity of naming similar celestial bodies.
