In 2005, astronomer Mike Brown and his team at Caltech discovered a new planet out beyond Neptune. Slightly larger than Pluto, the new object was nicknamed Xena (after the TV show "Xena: The Warrior Princess"). But is Xena a planet? For that matter, is Pluto a planet? Brown's discovery sparks a controversy over what exactly is meant by planethood. Turkish subtitles will be added soon.
