     The UK Exoplanet Naming

             Planet Competition  

As part of their centenary celebrations, the International Astronomical Union (IAU) is organising a global competition called Name Exoworlds.

In recent years, astronomers have discovered thousands of planets and planetary systems orbiting around nearby stars. The competition is to suggest a name for star WASP-13 and exoplanet WASP-13b. You must also provide a couple of sentences as to why you have chosen your names and the theme behind them. Please write this on a piece of paper and hand it to your teacher by Thursday 3rd October.

Please visit the website for more information.


The proposed names should be of things, people, or places of long-standing cultural, historical, or geographical significance, worthy of being memorialized through naming of a celestial object.

Although not necessary, it would be good if the names could be related to the UK in some manner. Also, the names may be drawn from themes related to the sky and astronomy or related in some way to the constellation that the exoplanetary system is observed within.

Two names should be proposed – one for the exoplanet and one for the star it orbits.

The two names should follow a common naming theme. The naming theme describes how the names are related in some logical way, should be summarized in a sentence or two, and be broad enough that additional names could be used to identify further objects in that exoplanetary system in the future (e.g. additional planets which might be discovered, additional stellar companions). Examples from the IAU include, say, rivers of country X or fictional lands in 19th century stories from country Y etc. but we are looking for as much creativity as possible!
