Marie writes: It's a long story and it starts with a now famous video of a meteor exploding over Chelyabinsk, Russia. Followed by alien conspiracies fueled by the internet and which led me to investigate further. Where did it come from? Does anyone know..? Yes! According to The NewScientist, the rock came from the Apollo family of near-Earth asteroids, which follow an elongated orbit that occasionally crosses Earth's path.That in turn led me to yet another site and where I learned a team of scientists had discovered two moons around Pluto, and asked the public to vote on potential names. They also accepted write-in votes as long as they were taken from Greek and Roman mythology and related to Hades and the underworld - keeping to the theme used to name Pluto's three other moons. And how I eventually learned "Vulcan" has won Pluto's moon-naming poll! and thanks to actor William Shatner who suggested it. Behold Vulcan: a little dot inside a green circle and formally known as P5.
