The International Astronomical Union (IAU), the professional body responsible for conferring official names on astronomical objects (among other things) has just opened up the final round of its NameExoWorlds contest. The initiative gives the public its first ever official chance to name planets and stars outside our Solar System, which is a pretty big deal when you think about it.
The names the public gets to vote on come from 247 proposals submitted by astronomy clubs and non-profit organisations around the world, with nominations from 45 countries in total. All up there are 20 planetary systems waiting to be named, comprising 15 stars and 32 exoplanets.
