Celebrating the 20th anniversary of the discovery of the first exoplanet in 1995, the International Astronomical Union launches a contest to name 20 new planetary systems. Only five stars, for having classical designations, will keep their names. Fifteen stars and 32 exoplanets are now searching for a name.

Nuno Santos, IA researcher, had a decisive contribution to the discovery of one of these exoplanets, located in the planetary system mu Arae. As an homage, Planetário do Porto decided to participate in this competition and propose names based on the Portuguese culture for this system.

The proposed names are:

Lusitânia (star mu Arae)
Caravela (planet mu Arae b)
Adamastor (planet mu Arae c)
Esperança (planet mu Arae d)
Saudade (planet mu Arae e)

Until the 31st of October 2015 (23:59 UTC) you can name these new worlds. With your vote, this planetary system can have Portuguese names!
