NASA just discovered a fourth moon orbiting around Pluto. The amazing thing to me is they found it by looking at it with the Hubble telescope. "Ah" you say, "but why is that such a big deal?" The new moon is between eight and 21 miles in diameter and Pluto is three BILLION miles away. In case you forgot those charts in grade school, that makes it almost 40 times further away from us than the sun. If my math is right, that's like being able to see the period at the end of this sentence from 124 miles away.
That's all the numbers I have for you today, hope you found it as interesting as I did.
