*Titan discovered 360 years ago*
On March 25, 1655 Christian Huygens discovered Saturn's biggest moon. It didn't get a name at the time, but nearly two centuries later got the very appropriate name of Titan. Huygens was a Dutch mathematician, astronomer, telescope-maker, diplomat, and all-around very clever person. You can read more about Saturn's planet-sized moon here:

The public can suggest relevant names to use on Pluto and vote for them. Here's the voter's guide and it's very interesting: I've learned lots of new things. The closing date is April 7, so don't procrastinate if you're interested!
