If you are looking to name something outside the solar system, a few exoplanets await you. The International Astronomical Union has a list of 20 exoplanets in need of a name. All you need to do is visit this site to vote.
For instance, four planets orbit mu Arae above and the voting allows you to vote in clusters, naming both the sun and orbiting planets. One of the naming clusters is shown below and has a Portuguese theme.
Voting is open until October 31 and the winners will be announced in November (the timeline and rules are here). Here is your chance to impact a whole new world.
