2015 will be the Year of the Dwarf Planet, and you need to tell people about it!

Emily Lakdawalla • March 05, 2014 • 11

I am very excited about 2015, more so than I have been about any year since I started working at The Planetary Society.

But if we want this kind of exploration to continue, I'm challenging you, dear readers, to tell the world why such non-planetary worlds are compelling places to go exploring.
